Be strong and stand up for yourself AND your daughter. Don't put up with that just because she's your mom.
It is so messed up that she would do that to you and treat you that way. There is no reasoning with someone like that, it doesn't matter if you tell her it's confusing being bipolar 200 different ways, she will still continue to abuse you. You're just a tool for her to make herself feel better about herself. She's is completely messed up in the head.

Why would her behavior make you lose faith in your medication? I don't understand that part. You need to stay on track and focus on yourself, don't fall off the wayside just because something gets hard for somebody else, because that is what this is. Your MOM is having issues that have nothing to do with you and you need to distance yourself from her.

I really hope you figure this out. Just stay strong regardless of what you decide. Also, welcome to pc. I hope you stick around.
