In my decades of seeking counseling, before my counselor changed professions, my anti-depressant meds came from my general practitioner, as they do now. My counselor did not write prescriptions, ever. But this person had to have a working acquaintance of some kind with prescribed substances.

My counselor had this to say about MDMA. Used heavily and consistently over time, it does something that the casual user would not expect. The casual user gets the temporary euphoria, resulting from MDMA engaging with a specific brain activity. But abuse/heavy-use of MDMA affects that very part of the brain in an adverse way, my counselor told me. That part of the brain, which has access to euphoria, becomes disabled instead. My counselor said: "It's a lifetime sentence of depression."
