I suspect my mother is BP but she wouldn't even consider it. She was in therapy and on medication for awhile when I was young but gave it up when my dad died. Now that I live with her again I see clear up and down patterns that affect her life because she'll isolate and refuse to talk to anyone for days. And we live with her so that's a feat. But she doesn't take it out on us usually.

Honestly I agree with MM. You can't force her to take meds. You can set up boundaries though. Tell her that you will not speak to her until she can speak to you in a calm, appropriate manner. You don't have to take verbal abuse from anyone. I don't talk to mostly my whole family because they just criticize me. I'm not putting up with that anymore.

Same thing with my own mom. We haven't been able to move out because of finances but when we are, I'm not going to talk to her when she's irritable and depressed. It's not my job anymore to make her feel better. It never should have been.
