Has anyone found help?

I am considering going to therapy to get help with my CSP which I've been doing for over 15 years. In the last couple of years it has gotten much worse and I'm desperate. I'm an ex-bulemic and a sober alcoholic. I have been taking 50-75 mgs of Zoloft for over 10 years. It helps with the anxiety but obviously not the picking. Therapy is very very expensive and I worry that I'd just be throwing money away. Has anyone found therapy or hypnosis helpful? Please advise.
