My mom said the worst thing she's ever said to me.

10. Maybe she is depressed and would do better with some meds to make her happier.

Some of my family were on such meds for the last years of their lives. My grandmother, who had worked so hard until she was 80, was on them in her last few years. She died at 103 and the calming meds she was on made her much easier to take care of. She was blind and deaf and had all her other faculties so for someone whose life had been so vital it was torture for her and she lashed out in frustration. So sorry for you.
