Not quite sure if I understand what you're saying.
Did you say I shouldn't have told her? Or that I should have told her in another way? Might be pretty right, cause the way I tried was probably the worst. Or at least a pretty bad one.

I might expressed that wrong. It's not like I get angry cause I'm depressive, but I get angry sometimes when I see how I mess up my own life. And she can't know why I'm angry in this case. Not that I would shout at her. I'm just very bad tempered and talking to me is not the best idea.
And of course depression is no excuse for anything. But it changes peoples behavior. A lot! Sometimes I loose myself in my thoughts about what happened and how stupid I am. When that happens, I just don't notice what happens around me and of course I don't response. And when I finished that, I have a complete other mood. That happens pretty often and she should know why.

I think I don't have to explain what depression is or what it changes.
