How can I stop thinking about it about the past?

I had bulimia and I still think Im fat I often think about startinng again and people in my class often make me feel bad about the way I look and half of them don't know what it is!they have started rumors about me saying Im emo and I cut myself I mean where the hell did that come from!?!?

It's not quite the same thing, but I went through a similar phase where I wanted to forget about the past and move on, but was unable to because of some half-wits. There have been 3 things that helped me get over it:

1. A group of trusted friends whom I could confide in
2. A family whom I could also turn to if my friends weren't around and
3. An internet blog.

Number 3 might surprise you, but whilst writing down all my thoughts and feelings in a blog, it felt cleansing in a way because I was able to tell someone or something just how I felt. It was even more encouraging to get comments back from people who had been through similar circumstances.

The biggest problem is that there will always be people who are small minded and think it's clever to make someone else feel small to make themselves feel better. It's very unfortunate that they've decided to target you, but these people will tend to prey on those who are different or perceptively "weaker" - even if you're actually a stronger person.

My first suggestion to you would be to keep a diary, whether online or not, of your thoughts and feelings and read over it after each week. Then, if you think things are becoming worse, ask someone to read what you've put so they can get a feel for what you're dealing with. At least then, you'll have someone to help you through it.
