I just found a link I thought might help you.
http://forums.psychcentral.com/showthread.php?t=184085 This is a thread that was posted in the bipolar forum, about silly things that we've done while manic. Everything posted in this thread would have been excrutiatingly embarassing at the time, or shortly after, but we can laugh about it now. I've posted a fair few embarassing moments in there. One I didn't post was being caught behind the book stacks in a college library at Oxford when I was supposed to be inputting data into the dewey decimal system. I've said and done such embarassing things that I've got used to...well, not making a fool of myself, but of not being ashamed of myself. Okay, so I went into a McDonald's restaurant dressed as a dalek from Dr Who, and got arrested for shooting fire extinguishers at the security guards. Okay, so I accidentally cut my long tresses so short you could see my scalp.
Embarassing things happen to everybody. It's part of life. At least yours will be interesting... give yourself time to stop feeling embarassed, then things will be much easier.
