Dear friend

I might also suggest that when you visit this forum, subscribe to few threads which matches your son's profile and when he is free sit along with him to discuss about it or better if you both read the issues together and discuss it. it will make him realize that he is not the only who has these issues. it will also make him realize how far his dad is willing to go to ease the suffering.

one more thing and this is for you my friend. dealing with depressed people can be tiring and exhausting. so please take care of yourself. make sure you get enough rest and just be happy. according to me a parent is the best therapist for a child.
