Well, yes. Bipolar II is primarily depressive. Actually, I think both are primarily depressive. A lot of times bipolar is misdiagnosed as depression. It is harder to catch someone manic, I think, because in mania most people are feeling really great. No one goes to the doctor for feeling too good.

Even bipolar people have mood swings because of reasons. They are called triggers. The difference is that a bipolar swing vs. a normal swing tends to be a lot more intense from what I understand. Harder to recover from, too.

Also racing thoughts and ideas are a big part of bipolar for a lot of people. They keep you awake, that's for sure.
