Can I get over my food aversions?

I have a very strong aversion to certain food textures such as potato (mashed, chipped, roasted, etc.), that causes me to gag violently. I am 22 years old and have a BMI of 16 which I blame in part to my very unbalanced diet. I am constantly lethargic but am eating three good portion meals a day. I was wondering if there was a way to get over this sensitivity as I am eating cereal without milk every morning, plain pasta for lunch and a pizza for dinner every day, I am looking to be a lot healthier with my life.


Is it dangerous to not drink water during sport practice?

I have a question about dehydration. I am an eighteen-year-old female and play on a varsity basketball team. We usually have two-hour practices in which we work very hard. Our coach does not give us water breaks, and usually by the end of practice, we have cottonmouth and are "dying" for water. It is horrible. Is there any way that not having water during that time can be dangerous? Sometimes the team can feel sick or weak by the end of a practice.


Is what I'm experiencing a urinary tract infection?

I think I may have some kind of urinary tract infection. It came on very suddenly, about three nights ago. And when I pee, there is a burning sensation when my bladder has almost emptied. It's not an STD because I'm in a monogamous relationship, and yes, I'm sure! Please help. Thank you.
