How do I make people understand that I DON'T have an eating disorder!!?

get your family and close friends around you and seek their help. If they really care they will help but you must be sincere, it's your life and your body to do with what you want but you need guidance and support from the people close to you. True friends will listen. Invite them over for a meal and be open with them,don't deny anything and don't lie to yourself.
