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 He is withdrawn and depressed a lot of the time.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

i believe he has some very deep insecurities and it will be very difficult for him to work them out... things stick with you from when you were younger, it is what defines you... if councilling didnt help try to get closer to him... NOT by trying to force things out of him but just invite him to do things with him and things like that and if he can work with you in his own way working things out and being loved in time he should be less depressed, but if he wont even talk to you, dont worry, perhaps you should talk to the councillor or you can go together but the most important thign to rememeber is to be understanding and always put yourself in his shoes befoee you open your mouth.
