My thoughts are with you and your son, Maybe you could talk about how much you care about him and would hate loosing him, and because of that you feel you have to do somethings he might not like, such as finding him a psyc, maybe find someone that specializes in teen boys, get him involved in the search for someone HE likes, I know from experience that if I don't like the person I won't open up. My dad was really helpful and found a lady who works with "young women" just for me she had a therapy dog and if I didn't feel like talking she'd let me pet the dog that day or talk to her through the dog I really liked her and having the dog there was wonderful it would always sigh after I got big emotions out.
