Bipolar mood swings can affect us anywhere but I am personally more likely to exhibit extreme behavior in places where I feel safe. If I'm manic I feel entitled to act how i want in places that are "mine" and if I'm depressed I want to be at home and miserable there.

When i was a teenager I fought endlessly with my mother and I think it's because I knew she would love me no matter how horrible I was. And also I was irrationally mad at her because I was hurting and confused and she couldn't fix it.

In addition to everything else he is isolating you, the car thing is really controlling behavior. I think this is one of those times when you list what you CAN do, like protect yourself. And what is not in your control, like getting him to take his meds.

Even if he was making healthy decisions for himself the most helpful thing you could do is take care of yourself first.
