If your pdoc can't help you directly, maybe he could recommend a counselor of some sort; someone you can talk to who can help you navigate your difficulties?

I would work on safe, healthy ways to engage the sexual and other energy instead of letting myself go into chat rooms, etc.; treat it as "energy" and work on tasks at hand longer, better. Figure out what a healthy eating plan and how much sleep you need (I "tested" myself in my 20's and found I needed 9 hours a night!) and how to get good sleep, etc. With hormones and growth happening as a teen, it is even more important to make sure the building blocks are well formed so you don't have as much trouble in the future!
