Okay. Can you help me with my horrible problem? Thanks and sorry it is long.?

I was watching television and all of a sudden I felt the urge to get a shower at 6:30. I did, and I went on Facebook. I looked at everybody's status and logged off quickly. I went to my room and cleaned my room. When I was done, I tried on pretty outfits taking pictures of me in each of them with my digital camera. I brushed my hair and teeth. Then I turned on the radio and started to exercise. In my mind I was trying to lose all my stomach fat and thigh fat. After 60 minutes, I got angry. It was like, I was felling all pretty, I looked down and I became mad at myself for being so careless with my eating habits. Now I know what I want. I want you to tell me how to lose all this weight. I hate my stomach and thighs. I am 13 years old, 5 foot (actually 4 foot 11 inches), and I weigh 148 pounds. I am not on any sports team, and it's too late for try outs. I tried everything. I drank more water and milk. I cut out chocolate and most sweets out of my diet. I don't eat many snacks anymore. I eat slowly, and I exercise for 10-20 minutes a day. Okay. Maybe I wasn't that honest. Whenever we go to the store, my little sister asks for candy. I don't want to get any but I do because she goes "Haha! I got candy and you didn't!" So, not everytime I go, I get some too because I don't want her to get the satisfaction of me not getting any. And, I eat sweets like little debbie snacks and ice cream. I do most of the diet stuff but I don't control my eating disorder. Every time I am bored, I eat something. Whenever I exercised, I eat something. When I'm sad happy or mad, I eat something. Whenever my dad asks if I want ice cream I say yes. I eat lots of sweets. My little sister is 7 years old, and weighs maybe around 47 pounds. She never frows out of her clothes. Everybody at my school is skinny but me. I only saw 3 other people that is fat, but 1 is a boy and the other isn't that fat, and the other one doesn't care. None of my friends are fat. I'm the only one. My mom is always telling me to exercise. I try, but never do. I hate the way I look and I want to change that. I want you to tell me how to fix that. I want to become 85 pounds the lowest. I am 148. Please help me! Also can you make it before school starts again, or before the pool opens? AND NO PILLS!!!!!!!!!!!!!!!!! Thank you and please can you help me? Thanks.
