I think that it is good that you brought it up and have given him the opportunity to pursue treatment. Given his age, I think it may be best to let him take it from here and decide to either go to therapy or not. This is my opinion but I have noticed that many people have better experiences (and possibly results) in therapy when they feel like they are in control and have a hand in getting better. After all, once he gets to the appt. its just him and the T from there. I think the best thing you could do for him right now would be to continue to show your support, hope and encouragement. You seem like a good parent.
