Mental institution for pornography. I gave in

A month ago I was admitted to a mental institution for porn addiction. I had stopped masturbating and watching porn for a year but after I saw my psychiatrist I was all emotional about it. So it turned out that I was experiencing post withdrawal symptoms. I've been on antidepressants since then. They seemed to be working at the institution but now I can't feel them. I'm angry, irritated, thinking a lot.
Because of my addiction I also used to force the girlfriends I dated into having sex without their permission. More like rape. My last girlfriend I used to take her out hotels to have sex with her. Guys what is really happening to me because I stopped watching porn 2 years ago and masturbation more than a year ago. It almost feels like these urges that I had for years are haunting me. I can't think clearly, I just buy a cigarette or buy alcohol to try and fill up this void. I'm really confused???

 

Ok

Okay man. Maybe I masturbated too much in my life that my body can't take the absitnence phase. I don't know?! My sister said the same thing. As soon as I finish exams I'll go back to see my psychologist. Thanks bra
