Are you sure?

But if bipolar is having weeks of [some BP symtoms] causing dysfunction, have will do nicely too.

I see it more as something continuous, qualitative, not quantitative.

I think my mind or memory, my emotional responses, something belonging to me, is disordered. Like having a part of you being cancerous, if you have cancer.

Actually having a condition is a bit strange, if you think about it, it's more being in a condition, so having a condition is maybe more about a part of you being in a certain condition, which wouldn't be like BP/bipolar.

But I think having a condition will do. It just sounds a bit scary.
