I need some serious help

[Blaine]

Hi there, i'm 17 years old and my weight's become a stressful issue in my life. The best way to describe my body shape is the well known "beer-belly" physique (all my weight's in my torso), and i'm looking for effective ways to get rid it (I have a gym membership which is largely unused so by all means suggest what equipment to use etc). Anyway, the bulk of my problem lies in the psychological aspect. I've been getting quite a lot of money recently (From education maintenance allowance, some relatives etc), but when I have money I can't help but spend it on junk (feel free to take the view that fat people arent addicted to food and are just greedy, but I can tell you first hand if it's worth anything, that I have a really agitating addiction, namely to Coca cola; in the past 2 days i've drank more than 2 6-packs of the stuff). I'm just wondering how people overcome the psychological aspect of their being overweight, because if it wasn't for that i'm sure I wouldn't be overweight now. All advice is appreciated guys
