I think you can just walk into the office & say you are depressed & you need someone to talk to. There may be a more subtle way to do it, but the important thing is that it gets done. You could try imagining that you are doing it for your brother instead of yourself. That technique has helped me sometimes. I have trouble doing things to take care of me too. When it is particularly difficult, I just ask myself what would I do if my daughter was in this situation? That helps me to see what the sensible action is, instead of the self destrucitve course of action, which I am good at taking. Hope this helps.
