i really need your help

Question
Hi, I'm 17 years old, 5'1" and 105 lbs. I was always really skinny compared to others at my high school, but lately ive began putting on all this weight and im not sure why. back in january, i was about 99 lbs, and ive gained 6 lbs since then... some of my friends told me this doesnt seem like a lot, but i can see a difference: mainly, my face has become rounder, my thighs/calves have become bigger, and my stomach bulges out. I also started taking a birth control pill every day to prevent acne, but I just started that about 2 weeks ago, so i know that the pill isnt the only reason im putting on weight (my doctor warned me i would probably gain 5-7 lbs after taking this pill). I already started gaining this weight at least two months before i started taking this pill. Im really desperate on getting the skinny thighs/calves that I had before, and i want my face to go back to being not-so-round. i work out everyday for about an hour at a gym -cardio/running, ab workouts, but nothing seems to be helping. If anything, i feel like my legs are getting BIGGER (especially my calves). I know there's more muscle there, but i also want to slim down. I dont know what to do anymore! If i dont do something about my weight (even though it might not seem like a big deal to some people), i feel like im going to lose interest in everything else besides my weight. All i ever see when i meet people on the streets are how skinny their calves are, and how slim and angular their faces are. It's driving me crazy, but I cant help obsessing over it unless I slim down! My tennis coach tells me to eat super healthy, but i dont know how many calories i should put in every day to lose some of that weight, or what foods to eat (I know to avoid junk, deep-fried foods, but i dont know what meats i can eat, etc)
Please give me some advice on how to:
1. slim down my face/get rid of all the fat thats making my face look so round
2. slim down my thighs (so my tennis shorts dont bulge so tightly around my thighs) and calves (i have HUGE man-like calves and its really embarassing when i wear skirts)
3. make my stomach flatter. (only my stomach bulges out a lot, while the rest of my upper body is pretty slim/small). I do ab workouts, but they only harden the stomach bulge i seem to have.
PLEASE HELP ME! Im so desperate! I'm not looking to become super skinny, i just need to lose this extra fat i have lying around!
Im really sorry this is such a long message, but I didnt know how to shorten it. Thanks for your time,
ali

Answer
You can't lose fat in just one area of your body.  When you lose weight you lose from all over.  As far as your face, since you are NOT over weight, I would guess that is just the shape of your face.  There is nothing you can do to lose fat specifically in your face.  Remember that you are still growing and developing so your body and parts of your body will continue to change.  If you feel your thighs and calves are larger then you would like them it could be the types of exercise you are doing.  You could be making them bigger by building the muscle in those areas.  Working with a personal trainer would be helpful in learning what exercises build what muscles and what you need to do to just tone up versus build muscle.  That would go for your stomach as well.
As far as eating, check out www.mypyramid.gov.  This will give you a start on healthy eating and how much you should be eating for your age, activity, etc...  
Everyone's body is shaped differently so don't compare yourself to everyone else!  Your body is YOURS and unique to you!  So do your best to just stay active and eat healthy and to take care of yourself.
