Nope, I can't hide it.

I went to an appointment with my pdoc this past Friday, and he almost immediately said, "you're hypomanic." lol

My parents notice my behavior as well. They tell me to "calm the f*** down". lol. "Why are you so hyper and smiley?" (Apparently I physically shake from excitement as well.)

Edit: my old bosses (I had two) noticed my hyperactive behavior and kept asking me why I didn't sleep, as I would work from 4am until 12am
