I'm so sorry that you're struggling with this, it's very easy to get trapped in. It's normal for girls to gain weight during puberty and the changes can be hard to accept for some people. I'm glad that you decided to reach out and that you realize that it's a problem. I would suggest talking to your parents, a doctor, or a counselor about what's going on. The longer you do it, the harder it is to stop. If you want to cut out junk food that would be a healthy choice, but don't become too restrictive. Food is not an enemy and eating doesn't make you "disgusting" or mean that you have to throw up.
