Hi everyone.

I am 21 years old and identified myself gay, since i was attracted to men. I was always against to my own homosexual desires and now I am. Till I was 18, I talked (dated) with 2-3 gays, and then I fell in love with one. We dated 2 times, both liked each other. Then I wanted to forget him, after I knew that he cheats on me. He tried to communicate to me several times, but I rejected him.

The problem is psychological issues in my health, because I cannot forget him even though 2 years passed. I have been living as a straight for 2 years, but my brain cannot stop thinking of him. I am sure I don't want any other man, even he is the best, I don't want anything that gays want, except for him. Just meeting and talking to him is enough for me.

As an outcome I cannot concentrate on my studies, work and other things, I often forget things that I have to do, pain in my head. 

I am always nervous because I cannot forget him, even I strongly want it, even I am so busy with many other activities and people.

How can I concentrate my mind, calm my nerves down?
