Can you diagnose my mental health or conduct psychotherapy?

No. Washington prohibits diagnosis and psychotherapy by hypnotherapists.

As a hypnotherapist, I am NOT credentialed to diagnose mental disorders or to conduct psychotherapy as defined in WAC 246-810-010.

"Psychotherapy" means the practice of counseling using diagnosis of mental disorders according to the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM), and the development of treatment plans for counseling based on diagnosis of mental disorders in accordance with established practice standards."

I can refer you out if needed, but these things are not particularly useful in the practice of Subconscious Behaviorism or Hypnotherapy anyway.
