Sorry though I am for what happened to your mother (I am very aware of the dangers of pregnancy being a type one diabetic myself), your brother is his own person and should not feel obligated to live his life the way anyone else wants him to. It seems to me that there is an air of ' our mother died for you, make her proud' hanging over all this which would frankly be an intolerable burden for anyone. I'm not surprised he's depressed, he hasn't got to honour anyone else's wishes for him, he is his own unique being. I really do hope that you sort this out, it must be so hard for both of you. x
