Hi, I'm not sure what kind of eating disorder you have, or any other details, so it is quite difficult for me to help you. The best I can do is guide you in a nice little direction to help you out, but other than that, I wish you luck in the future.
Eating Disorder Information
Under "Treating Eating Disorders", this website says this:
Treatment focuses on helping kids cope with their disordered eating behaviors and establish new patterns of thinking about and approaching food. This can involve medical supervision, nutritional counseling, and therapy. The professionals will address a child's perception about his or her body size, shape, eating, and food. Kids who are severely malnourished may require hospitalization and ongoing care after their medical condition stabilizes.
Generally, the earlier the intervention (ideally, before malnutrition or a continual binge-purge cycle starts), the shorter the treatment required.

I pretty much want to repeat all of this website, so, I'll quote part of it that I feel are important. Getting Help is obviously something you need to do right now.
One of the hardest things to do is admitting and accepting that you have an eating disorder. The next hardest thing to do is reaching out and asking for help. 
You realize you have an eating disorder, now, have you asked someone to help you? This is mucho important.
It is important that you find ways that are helpful for you. Many people will try to tell you what you "have" to do in order to recover, but only you know what methods of treatment are best for you. What works for one person, may not work for another. Do not be afraid to tell people what you want and need. 
Recovery is a long road and remember that you do not have to travel that road alone. It really is important to reach out for help. There is no shame for having an eating disorder and help is available. You do not have to be a prisoner to your eating disorder forever. Not only is it okay to ask for help, it is necessary. Below are some sections that I hope will be of help to you or to a loved one as they begin getting the help needed to assist them in their recovery. 
Really, this are very important quotes that you need to think about. Understand what they are saying, and act upon it. If you feel the need to submit another eHelp to give more information, that is great! Remember that eHelp Support Leaders are NOT trained professionals and you need to consider what they say before taking any "advice" they may give. Good luck!
