Do i have an eating disorder

Patient: For a long time ive never liked the way i look and i guess i have always skipped meals but just recently ive been eating less because i feel sick if i eat atleast a whole meal, and for a couple of days ive been putting my food in two piles 1 i will eat the other i will put in the bin. i constantly feel fat and low about how i look but i dont think im losing weight but others think i constantly tired and sometimes if im hungry i dont eat i just have something to drink.also when i was younger i was underweight but now im a size 12 but do i have the symptoms of any eating disorders?
