How do you know if you have an eating disorder? I avoid meals at school and hope that no ones notices. The only meal I do eat is the one my parents cook for me, and I measure out my smaller portions of it. I never saw it as an issue, but I am constantly checking my weight and becoming angry at myself when I haven't lost weight. I just put my lack of eating down to be being stressed at school while doing my a levels. But I just don't know if it's a problem?
