My hypomania turned ugly Saturday, I was able to fake being nice at my friends wedding even though I was swearing at other friends...
Today its been horrid, snapped at my daughter, which was a total overreaction, so I put in earphones, had the metal on max, and forced myself to sleep some of the agitation off.
There's a reason doctors sedate us, sleep helps to reset or atleast take the edge off.
Try something calming and soothing, if its at the point where you wanna slam your head into a wall, physical exhertion helps a TON, exercise, cleaning, dancing, your choice.
Hope you feel better soon
