I Was Always A Picky Eater When I Was Younger,

I was always a picky eater when I was younger, but now It's getting ridiculous; I have a very, very limited amount of food that I like and the list is getting shorter each month. And it's not longer just "no, I don't like that", it's to the point where if I don't like something I literally CANNOT swallow it. My throat will kind of close up and I can't breath until I finally force it down or I spit it out. It's almost as if I have some allergic reaction to any food I don't like. Is this some kind of eating disorder?
