Your treatment path

How do you get to a treatment-resistant diagnosis?

Care isn't one straight line. Here's how the path branches — and when first-line treatment isn't enough, what your options are.

Comprehensive evaluation
History, symptoms, goals, and what's been tried before.
First-line treatment
Therapy and/or medication, matched to your diagnosis.
After 6–8 weeks — is it working?
If it's helping ✓
Continue & maintain
Ongoing medication management, therapy, and follow-up to protect your progress.
If it hasn't helped enough ✗
Treatment-resistant depression or anxiety
When two adequate trials — right dose, enough time — haven't worked, that's treatment-resistant.
What are the options now?
Chosen together — a menu, not a ladder. No single treatment is automatically "next."

In our clinic

We provide medication management, therapy, TMS, and Spravato in-house, and refer out for the rest. Which options fit depends on your diagnosis — TMS and Spravato are FDA-cleared for depression, while treatment-resistant anxiety is treated mainly with medication and therapy strategies. Candidacy is always determined clinically.

Conditions

Conditions we treat

We care for the full range of psychiatric conditions — with particular focus and depth in treatment-resistant depression, treatment-resistant anxiety, depression, anxiety, and ADHD. Every condition gets evidence-based care.

Treatment-resistant depression

Depression that hasn't responded to two or more treatments — where TMS and Spravato can help.

Anxiety

Evidence-based medication and therapy for generalized, social, and panic-related anxiety — including anxiety that hasn't responded to first-line treatment.

Depression

Medication management and therapy for major depressive disorder.

ADHD

Comprehensive evaluation and ongoing management for adults and adolescents.

OCD

Medication, referral to ERP therapy, and Deep TMS for OCD that hasn't responded.

PTSD

Trauma-informed treatment for post-traumatic stress.

Bipolar disorder

Diagnostic clarity and mood-stabilizing medication management.

…and more

We treat the full range of psychiatric conditions — if you're struggling, reach out and we'll help or connect you to the right care.

If standard treatment hasn't worked, you still have options.

Not responding to the first treatment — or the second — is more common than people think. We'll help you find what actually fits.

Who am I

"Within the depths of my ADHD lies a Hidden Power, unlocking the extraordinary potential… nurturing the inner flame, transcending perceived limitations, and defying expectations while inspiring others along the journey of self-discovery."

Nefretiri Abat, J.D., PMHNP-BC

I am a board-certified Psychiatric Mental Health Nurse Practitioner, licensed in California to diagnose psychiatric-mental health conditions, prescribe medications, and provide psychotherapy. I earned my Bachelor of Science in Nursing and Juris Doctor from the University of Santo Tomas, and my advanced practice degree from Walden University.

Since 2004, I have worked extensively across inpatient acute care and behavioral psychiatric units — adolescents, acute adults, geriatric med-psych, and psychiatric intensive care — centered on the significantly impacted, underserved population. I specialize in depression, anxiety, substance use, and ADHD, grounded in a harm-reduction, trauma-informed, whole-person model. The care I render is always client-centered and non-judgmental.

Frequently Asked Questions (FAQ)

Answers to common questions about psychiatric consultation, TMS therapy, Spravato (esketamine), and treatment-resistant depression at Exxceed Wellness in Hayward, CA. This is general education, not medical advice for your specific situation. If your question isn't answered here, please contact us.

General Psychiatric Care

What conditions does Exxceed Wellness treat?

We provide psychiatric care for depression and treatment-resistant depression, anxiety, OCD, and ADHD. Alongside medication management, we offer two interventional treatments, TMS and Spravato (esketamine), for depression that hasn't responded to standard care.

What happens at a first psychiatric consultation?

Your initial visit is a thorough evaluation. We review your history, current symptoms, past treatments, and goals, then discuss the options that fit your situation and build a treatment plan together. It is a conversation, not a quick screening.

Do you see patients in person or by telehealth?

Both. Our clinic is at 21297 Foothill Blvd, Ste 203, Hayward, CA, where in-office treatments such as TMS and Spravato are provided. We also see patients by secure telehealth across California for services that can be delivered remotely, including consultations and medication management.

Do you provide medication management?

Yes. Starting, adjusting, and monitoring psychiatric medications is a core part of our care - on its own or alongside TMS or Spravato.

Do I need a referral to be seen?

No. You can schedule directly with our practice. A referral from another provider is welcome but not required.

TMS Therapy

What is TMS, and what conditions is it FDA-cleared to treat?

Transcranial magnetic stimulation (TMS) uses focused magnetic pulses to stimulate the brain regions involved in mood regulation. It is non-invasive, medication-free, and done in the office. TMS is FDA-cleared for major depression (including treatment-resistant depression), anxious depression, and — as an adjunct — OCD; our Magstim Horizon 3.0 carries these clearances.

Does TMS hurt, and how many sessions will I need?

Most patients describe TMS as a tapping or knocking sensation on the scalp rather than pain; mild scalp discomfort is the most common side effect. A typical course is five sessions per week for about six weeks (roughly 30 to 36 sessions), followed by an individualized taper.

How long does a single TMS session take?

Active treatment can run from about 3 minutes with newer theta-burst (iTBS / Express) protocols to roughly 20 to 40 minutes for standard protocols. With check-in and setup, plan for a short in-office visit each time.

What is the difference between standard rTMS and iTBS?

Standard rTMS uses a figure-8 coil to target a focused area. iTBS, or theta-burst, is a faster stimulation pattern that delivers treatment in just a few minutes. We match the protocol to your diagnosis and coverage.

Does insurance cover TMS in California?

TMS is often covered by California commercial plans for treatment-resistant depression, typically when there is a documented history of antidepressants that did not work. Plans generally require prior authorization, and we manage that process for you.

What happens after I finish my TMS course?

Many people maintain their improvement after completing a course of TMS. For others, occasional maintenance sessions or a relapse-prevention plan help protect the gains. We talk through what makes sense based on how you respond.

Spravato & Ketamine

Do you offer ketamine therapy?

We offer Spravato (esketamine), an FDA-approved nasal-spray form of ketamine for treatment-resistant depression, given under monitoring in our clinic. We do not provide IV, intramuscular, or compounded oral ketamine. If you are researching ketamine for depression, Spravato is the ketamine-class treatment available here.

Is Spravato the same as ketamine?

Spravato is esketamine, the S-enantiomer of ketamine. It is FDA-approved specifically for treatment-resistant depression and is given as a nasal spray in a certified setting. This differs from racemic IV ketamine, which is used off-label for depression.

How does a Spravato session work, and how long does it take?

You self-administer the nasal spray in our office under supervision, then stay for monitoring. Because of how Spravato can affect you, you are observed for at least two hours after each dose, so plan for roughly two to two and a half hours per visit.

Can I drive after a Spravato session?

No. You cannot drive for the rest of the day after each Spravato session, so you will need to arrange a ride home.

How many Spravato sessions will I need?

The induction phase is typically twice a week for about four weeks. After that, sessions are spaced out into an individualized maintenance schedule based on your response.

Is Spravato covered by insurance?

Spravato is often covered for treatment-resistant depression with prior authorization. We help manage the prior-authorization process and verify your benefits before treatment begins.

Treatment-Resistant Depression

What is treatment-resistant depression?

Treatment-resistant depression generally means depression that has not improved after at least two different antidepressants taken at an adequate dose for an adequate length of time (often 6 to 8 weeks each). Only a clinician can determine this, so the best next step is an evaluation rather than self-diagnosis.

Spravato or TMS: which is right for me?

There is no one-size-fits-all answer. The right choice depends on your treatment history, lifestyle, side-effect tolerance, insurance coverage, and clinical judgment. In some cases the two can be sequenced or combined under clinical supervision. We help you weigh the options during a consultation.

What should I do if my depression starts coming back after treatment?

A returning symptom is a signal, not a setback to face alone. Reaching out early, when sleep, energy, or mood first start to slip, gives us the most options, from adjusting your plan to considering maintenance treatment. Contact us promptly if you notice warning signs.

Anxiety, OCD & ADHD

Can you help with anxiety?

Yes. We treat anxiety with evidence-based options, including medication such as SSRIs, SNRIs, or buspirone and structured therapy approaches. TMS is not FDA-cleared for generalized anxiety, though it is sometimes considered off-label; we discuss what fits your situation.

Do you treat OCD?

Yes. OCD care combines psychiatric medication management, referral to evidence-based ERP (exposure and response prevention) therapy, and — for OCD that hasn't responded to those — focal TMS on our Magstim Horizon 3.0 (FDA-cleared as an adjunct for OCD; this is not BrainsWay's Deep TMS). We determine the right approach based on your symptoms and history.

Do you offer ADHD assessment and treatment?

Yes. We provide comprehensive adult ADHD evaluations using a clinical interview, validated rating scales, and history, in our Hayward office or by California telehealth, along with treatment and medication management when appropriate.

Fees, Insurance & Getting Started

Do you accept insurance?

We work with a range of insurance providers, and interventional treatments like TMS and Spravato are often covered for treatment-resistant depression with prior authorization. Coverage varies by plan, so we verify your benefits before your appointment.

What if I do not have insurance?

We offer flexible self-pay options and will discuss costs upfront so you can make an informed decision about your care.

How do I get started?

You can book directly through our contact page or call (415) 636-9700 (Mon-Fri 8a-8p, Sat 9a-5p). We help you choose the right first appointment and verify any insurance benefits before you come in.
