Do I have an eating disorder?

So Im really not sure if I have an eating disorder Ive tried to research as much as could for my symptoms but I cant really find anything so I thought Id make a post to see if maybe anyone else is experiencing this, so a I would say a couple months ago maybe 4 months I was eating normal, probably actually more then normal because I was smoking weed and just eating but I was gaining weight from it so I slowed myself down on the food but now Ive gotten to the point where Im not eating really anything during the day and Im not even really getting hungry, but then when I try to eat a meal at dinner time I take few bites and I feel really very full, and then I start to feel like I need to throw up because I ate so much but I really barely ate anything, i cant help but think to myself that Im not eating because I dont like my body but at the same time Im never hungry.. I had read a post today saying that your mind can have an eating disorder before you even know it. Im really not even sure if anyone can even help me but worth a shot
