You might be able to focus the anxiety into a success. My son had lots of anxiety about being good enough. I mentioned activities as this turned into a positive outlet for my own son. He discovered soccer and he discovered running - and that all of his energy positively affected his ability. He was able to turn anxiety around into a success. He still obviously worries about things but his life is still wrapped around these same activities. In fact, he made such a success of it he has managed to forge a career out of it. Basically, he found a way to turn the negative into a positive.

I truly hope the best for your own teen and that he finds a drive in something he can focus on.
