Sounds like bipolar 2 to me as that's similar to what I go through when I'm hypomanic.

My understanding of the difference between bipolar 1 and 2 is that in bipolar 1 you're crazy high for lack of a better word to where you're out booking passage for everyone you know on a cruise around the world, and the like. With bipolar 2, you feel great, are very confident but aren't completely out of control--you're obviously far more impulsive than normal but not a crazy lack of control.
