What city do you live in? Maybe if you share that some people here could give you a good therapist referral - and the therapist can give you suggestions for a psychiatrist to perhaps try some medication in addition to counseling.

Carl Rogers was an interesting guy and he had a scientific approach (as I like understand how things work). It's a model that fit well to my mind.

I guess all models have nearly the same success rate.
