I went through your details. I suggest you not to worry much. I request you, please understand that self diagnosis and self treatment can cause more harm than cure. Especially in the case psychiatric drugs, it is dangerous. Please consult a psychiatrist for any treatment.
Addiction, what ever may be the case, is addiction. Here you have an addiction of habit, and body is not involved. Therefore, altering your life style and keeping your busy and having a good hobby can cure you, along with a will to succeed.
If you require more of my help in this aspect, Please post a direct question to me in this URL. http://goo.gl/aYW2pR. Make sure that you include every minute details possible. I shall prescribe the needed psychotherapy techniques.
