Oh yeah. In my teens I was extremely anxious, especially in social situations, then I started getting hypomania and all that went away and I would go up to people I don't know, ask them if they wanted to throw pumpkins off the roof with me, and then dance with them. There is nothing about that I would be comfortable doing without hypomania.

Full blown mania for me, on the other hand, involves more anxiety than I care to think about.
