No, I'm not. While I would appreciate help in such a situation, I can fully understand anyone walking away. Being a bother to people and needy is one of the worst parts of being ill.
Thinking your depressed friend is a bother to yourself has told me that I'm very blessed you and I are not friends.
If you have a treatable form of depression, go get treated. If you have a personality disorder, the person you're responding to is the lucky one, not you.
