Could I have an Eating Disorder?

I'm 14 years old, and everytime I eat, I begin to feel noxious. I looked up the symptoms before writing this, and I found that some people had Eating Disorders, but also, they had to much stress.
Here are my symptoms:
-Half-way through eating, and afterwards, I feel Noxious for hours afterwards.
-My body doesn't seem to want me to swallow the food that I'm eating.

And I eat pretty healthy for my age. I eat a mixture of foods each day. I never eat balanced meals though.. I skip breakfast and lunch almost everyday because I'm never hungry at those times. But when I get home from school at about 3, I eat a snack. But then I go to eat dinner around 6 and I can never finish it due to the nausea.
So can anyone please help because it's really starting to bother me.. Thanks :)

No, it does not sound like an eating disorder.  You should see a gastroenterologist because your gut seems unhappy.  I do not think it is stress-related.  Just assure the doctor you don't feel stressed out or have any emotional issues; you just have no appetite and you are having digestive problems.  If they want to do tests, they might sound bad, but the ones I have had actually went quite well.  If they do an upper endoscopy, they will give you drugs so you don't remember it.  You need to find out what is going on now, before your nutrition suffers.  That will open you up to bigger issues down the road that could have been avoided if you just took care of this in a logical manner now.
