If you think you have a problem, you maybe do. There are some behaviours that are really distressing you to make you think this.

It is sooo much easier to get treatment early on and get better before you damage your body, even if you are a healthy weight and don't binge, purging can cause permanent damage to your body and people die from it because it alters your electrolytes which can stop your heart - That doesn't mean you have to put your life on hold and go to hospital or tell everyone about your problems, start with going to your doctor, or maybe a counsellor at college.

Best of Luck
