First, I think this post was a good idea, and thanks for taking the time to write it and for putting yourself out there.

Consider reading about http://en.wikipedia.org/wiki/Cognitive_behavioral_therapy, and see whether that was the strategy which your therapist used. If not you might want to broach the topic with your parents and see whether they'll find you a therapist who will use CBT. Worth a shot, although it's [not necessarily efficacious in depression].

On the other hand CBT does not work for all people. I'd really suggest for you to have and/or "buy" some fun. Selfishness in the short run is often for the good of everyone in the long run.
