You seem kind, peaceful, and loving. With that attitude and determination I imagine you could approach almost any discussion you wish.
In my group, I am the one that tends toward depression. The only thing I can tell you that helps me is that my partners don't give up on me. Sometimes just knowing that can pull me through difficult periods. I need to see my value through the eyes of others, when I don't see the value in myself.
I wish you happiness.
