I overreact sometimes whether I am manic or depressed, the smallest thing can get me going, unfortunately I usually take it out on my wife. When I calm down and apologize, she accepts it, but I will still worry for days if not a week about going off on her. Then when I try to talk to her again about it, she has usually forgotten about the whole episode.

Good luck with getting this under control, I was almost happy (that doesn't happen a lot these days) to see all the posts of people with the same problem, you are not alone.
