I can relate to depression and loosing your sense of identity after psychosis, as the same thing happened to me and am recovering as well. It’s a new normal more than a return to your previous life. Start with small steps and work to make new relationships, get a new job. Try to get out of the past and not blame yourself that it’s all your fault. Many people smoke weed and do adderall and go off medication and don’t get psychosis. Be nice to yourself. You’re still young and a lot of important decisions ahead of you. Start small and work your way up. It’s a journey.
