Eating

Lately I havent been eating much food and whatever I do eat I make sure to throw it all back up. I know this is wrong but I can’t help myself I hate my weight! I hate the way I look! I have become so obsessed with my weight over the past like 2 weeks it’s getting obsessive. I know that I am bigger than most people and I want to loose it all. What do I do I’m scared! Is there something wrong with me?
