Its hard to say dude... how to cure a soul? I believe that counseling may be helpful, but dont underestimate your own mind. Yes.. its true the problem is in your head, but i believe that -you are your best T- and yes, drugaddicts are far more common 'cause everybody is a drug addict (to coffe, nicotine, sugar..). And rehab for tormented minds just freak out people.
Keep on the daily sessions, and good luck!!!
