I wonder if the stress about whether or not you can or should work, and what the future holds and the disability issue is causing some of this. I wish I could help you. I, too have taken meds that work great at first and then stop working. I am on a new medication now and I hope and pray it works. I am close to your age. I don't know if depression hits us differently when we reach age 50 or 52? I also deal with the paranoia and inability to trust people, especially at work. I would definitely see your pdoc and social worker and tell them what is going on. Best of wishes to you.
