When I am in the depressive side of things I am easily irritated, and annoyed. I have to really try to select my words as I will say things that are insulting or hurtful to people around me if they are getting on my nerves. I don't intend to attack them or hurt them, but my mood can be so gritty and cynical that I cutting words just flow from my mouth. So yes I may not remember saying something so rude, because I may have dialed down what I was going to say.

As far as my triggers for those attacks. Pretty much if somebody wont leave me alone, or pushes an issue while I am in that mode then I will get nasty with them. I go into isolation to protect their feelings as well as mine.
