From what you describe I'd say going the disability route sounds like a decent idea, its not a wonderful income but if you're issues are so severe it interferes so much you couldn't work then at least it is something. It does sound frustrating having a mom who is that dismissive and doesn't seem to acknowledge that you're really struggling......perhaps with being on disability you could move out, probably would have to have a room-mate or something as it might not be enough to pay rent in full somewhere on your own. But just thinking living with your mom isn't doing a whole lot for you.
