You definitely need to get in touch with a psychiatrist. This isn't something just talking will help. While your mother is understandably frustrated, I think you and she, and your sister and others who live with you, need to be in family couseling, because cursing at you and calling you stupid is verbal abuse, and not helpful at all. It's not just your problem and your duty to get well. They're your family, and this is their problem, too, and they have to help you.

If your medications are a problem, tell your shrink. There are probably others you can try.

Best of luck to you. I know it's awful. I wish I could cure you.
