Hello, nousername101, and welcome to Psych Central! I'm so sorry your mother is not taking care of herself. I assume she doesn't like the side effects of her meds. It would concern me, too, that she says now that she's not sick and so doesn't need medicating.

Does she have a psychiatrist? I suggest you call this doctor and tell him/her what's happening. If your mom is suicidal, then she can be involuntarily committed to a hospital and get treatment. Could you handle that? (I know it would be hard, but it would be for her own good.)
