I think I have binge eating disorder?

for the past week I've been eating a lot of food, Saturday night I had a cupcake, ice cream, and a trix yogurt. Im eating constantly because I'm always hungry , I feel like I have no self control because when I try not to eat I give in and eat anyways and even when I eat healthy food I feel guilty. I mean what exactly is clified as binge eating disorder? I need to know If I have it and how to cure it.
