I don't have Bipolar, but I definitely have a big pacing problem. I've had it for years, every time I get stressed or any kind of negative emotion. We have this big table in the dining room, and I'll find myself not even noticing that I'm pacing around and around and around it. I rarely ever sit down and have meals, I usually find myself pacing around while I'm eating actually. My family gets onto me about it all the time, especially when I do it at night and they'll say they couldn't sleep because I was stomping around all night. It's almost like dissociation for me, like my mind leaves my body and I'm just pacing and pacing with no control over my body or thought to stop it. So you're definitely not alone.
