Am I doomed to be forever underweight?

[NDemaree]

First off, I'm 16 y/o, 6' tall. I weigh 130lbs. I should probably weigh 160ish. I'm also probably one of the pickiest eaters ever born--There isn't a single vegetable I like, I actually can't even manage to get vegetables down. I vomit every time I try. There's 2 types of fruit I like, which I can't even eat; apples and bananas. My teeth are bad, and would actually come out if a tried eating an apple, and all of the sudden I became allergic to bananas... My diet consists of almost nothing but noodles. Just buttered noodles, I don't like any kind of sauce, even. On occasion, I'll eat something different, but it's never any better. I don't eat much either, I skip breakfast and sometimes I even skip lunch. I don't drink a whole lot either--probably 2 cups of water a day, and a few sodas. So a healthy diet is almost impossible for me, and I can't exercise much either. I have an odd skin condition that makes me itchy when I get hot, except it isn't 'itchy', it's more of a 'I'm getting stung by hundreds of bees everywhere all over' kind of feeling. So am I just going to have to deal with being eternally underweight?.......

You need to see a doctor for several issues that you are having, including weight, allergies, teeth, and eating/drinking problems.  See your parent(s) or guardian and request they make an appointment for you because of your general health.
