“Just Take Your Meds and You’ll Be Fine” ?? Wouldn't it be nice if this really worked!
I am sorry your mom is hesitant to talk about this. There must be a genetic component to bipolar so if you could talk to her (compare experiences and lessons learned) it could help you and future generations in your family. Don't give up on seeing if she might talk more about this someday.

Though I sometimes wonder if I am to open about my mental problems in general--mostly I have decided that it is good to be open about it. I am glad that you are sharing your story!
