What can I do to help my 17 year old son? He is withdrawn and depressed a lot of the time. More info provided?

maybe try to do activities with him like play a game he likes, that way he might open up and talk. maybe find a different consellor because sometimes it takes two or three before you find a good fit. and also you could try to talk to him straight on, ask him questions but in a gentle way, if he gets annoyed stop talking about it and try again later. hope this helps a little!
