Please be sure to have THOROUGH ENDOCRINE WORKUP - not just THyroid! Sex hormones, cortisol, autoantibodies. If you have been on SS/NRIs and other drugs for "treatment resistant depression" and not responding, the drugs may be worsening you and underlying endocrine or other condition. I went thru 20 years of drugs to find out my endocrine system was shutting down, Lupus undiagnosed. CBT worthless.
I hope you have found help! @nancychicago
