Disclaimer: I have bipolar II, and hence have never been full-out manic. However, while hypo I have:

-rearranged my room at 3:00 AM
-decided to change my major (was actually a good decision!)
-thought about getting through college in 2.5 years total (possible w/ my AP credits, but not a good idea)

-planned out the courses I'd have to take each semester if I were to triple major in neurobio, psych, and philosophy. (Not going to follow through with that plan...)

-thought about taking a year off from school, moving to Scotland (from the US), and writing a novel. I even found a cute little cottage in Inverness, and asked someone from my dorm if she'd like to move there with me because I couldn't afford the rent alone and I knew she had no plans this next year. (She said no, so that didn't go through...)

I've never done anything sexual and crazy, though that may be because of my religion, and the fact that I've never gone beyond hypomania...

I've enjoyed reading everyone's stories!
