Sounds like your hypomania started out as exciting and positive in some ways and now it's turning bad on you, which I can definitely relate to. When I get like that I increase the Seroquel (which I see you take) and that can definitely bring me back down to baseline, though then very very sedated.

When I've been well for a while I very slowly titrate it down again. This is all with the blessing of my pdoc though she gives me the titration schedule, so I don't do it too quickly, which is what I feel like doing at that point.

I definitely understand your worry about how others think of you and what that can do to one's self esteem given your behavior (I've been in the same boat, with depression as well). Hopefully they will be forgiving and understanding that you are just not yourself at the moment. Please try to remember that this too will pass and hopefully you'll get back to baseline and not crash. Everyone's different, but as I say, I up the Seroquel.
