I have the same diagnoses as you. I also became a Heroin addict after cancer/Crohns treatment and being kicked out of my own startup. I can’t encourage you any more heavily to explore CBT if you haven’t already. Changed my life for the better. (Same with Vipassanā meditation but I’m hesitant about how some adherents/practitioners treat it as a cure all salve.)
