What can of help can I get for my addiction?

I started playing World of Warcraft in January and have noticed a huge weight gain and loss of energy. I have that problem almost taken care of, but because of my lack of energy and motivation that I developed, I am addicted to fast food. I eat fast food everyday, at least twice a day. I will eat dinner at home, then leave to go to work, and I have to stop somewhere to eat. After work, I have to stop on the way home to eat something, I can’t help it. Is there an organization like AA that is for people with fast food addiction. I’m still not that overweight to where I would say I have a weight problem, but with the way I am going, and the fact I still play warcraft a lot and not working any of that fast food off of me, I am scared I will start to develope something bad. Thanks for the help.
