I have this addiction with an "imaginary life"?

[(x+a)^n=∑_(k=0)^n▒〖(n¦k) x^k a^(]

Okay I have this… problem, if you will. Where I basically have two lives; one being my real life and the other is just an imaginary life.
Lets start with my real life. I have an average amount of friends only had a relationship with another once. But only 2-3 friends that actually call me up to hangout. However their dorming at college now so I rarely go out. I also have a facebook with only a group of people I usually chat with. I was never employed with any type of job and pretty shy.
Now my imaginary life. In my fake life I have many friends whom I hangout with a lot. Sometimes through games or just getting some lunch/dinner. I have a girlfriend whose name seems to change everytime (I guess depends on my mood).
Now the problem. When I am on the computer and ran out of things to do I just sit listen to soothing music and go into my fake life hanging out with some friends and have imaginary conversations with these people created in my head. I also go in the state during classes at school when I’m bored, when I’m eating, or while taking a shower. I also have these imaginary thoughts before going to sleep. I will admit that I enjoy my imaginary world more than my real life. My imaginary life time goes according to my real life so basically its, I guess like a portal to another world…(?). There are no crazy stuff that goes on my imaginary like flying cars and whatever. Its just a life I will want to have one day. When I dream on during class I usually imagine myself sitting in class chatting with a couple friends or knowing the answers to my work. I tried erasing these imaginary friends from my brain but when I see pictures of my (real) friends on facebook just hanging out or having a good time, my imaginary friends come back and I make pictures of my own.
Yes, this seems kinda crazy, I have been having this issue since the January 2012 but didn’t happen too often back then. Since the beginning of college, around June, I’ve been having these imaginary thoughts more often. Anyone know of this…problem and how it can be solved?
please help.
