I think I have a binge eating disorder?

I am a 29 yr old male and have been binge eating since I was about 15, which got far worse from the age of 22. For some unknown reason, I looked at what I was doing to myself and looked up for help and realised that I fulfill every criteria of a binge eating disorder. There are some times in my life that clearly point to why I started and have given me the poor self image that I have today such as child abuse, and 2 cheating girlfriends. My sex drive with my lovely girlfriend of 2 years is pretty non-existant

To give you an example, last night instead of eating a dinner (I live on my own) I went out and deliberately bought a binge feast and ate a whole loaf of fruit bread, a large toffee sundae dessert and two cream cakes and I felt like crap emotionally and physically straight after and hate myself for doing it but can't stop. This happens at least 3 times a week :,(

I don't want this to control my life any more and I want a fresh start. I don't feel like I want to speak to my regular GP to be talked into excercise, diets, drugs, etc. What I think will help me the most is support, talking, advice, suggestions from people who know about eating disorders and can't help me solve the issues i have BEFORE trying to lose the weight. I live in Essex in England and would love for anyone to provide me advice on where to go for this help. Also anyone with the same experiences to comment would also be great.

I know this is my first step in admitting a problem and i want it to be a positive one because I know this will kill me. I am already over 18 stone.
