think i might have an eating disorder

Hi

I dont feel like eating anymore and have to force myself to eat , I have to have skimmed milk , as can really taste the fat in semi - skimmed milk. I deffinately do not want to gain weight at all . I have been told my legs are really skinny , yet i dont think they are . Im a healthy weight for my height of 5ft2 , and my BMI is healthy. I think people are trying to sabotage my weightloss efforts and they are jellous. I exercise alot , sometimes doing quite a number of fitness classes in one day. I feel really fit , yet people keep saying ive lost too much weight. I will admit sometimes i feel compelled to exercise, and i get extreemly anxious if i cant workout or i miss a workout. I just dont feel hunger anymore , please help


Thankyou
