HOW YOU THINK YOU BECAME ANA/MIA:just dieting, getting out of control

heres my story- when i was 13, my weight soared up to 190 and that's when i started dieting. weight watchers helped me lose 10 pounds and over the next year or two i lost another 20 just by cutting back. last summer, my dieting started getting out of control. i started eating small "meals" such as a piece of cheese or fruit cups. when i wanted soemthing good, like a piece of cake, id chew every bite and then spit it out. if i could, i would make myself throw up, i have tried, but i just cant. so throughout this past school year i lost another ten pounds and this past spring got down to my lowest weight of 143. but since track season has ended and since ive been out of school for the summer, i've gained 7 pounds and am now 150. i dont feel like i am too overweight but i want to get down to lowest and then exceed that. i want my bones to show. i love seeing pictures of nicole richie and lindsay lohan. i love knowing that my family and friends are worrying about me and that im getting this attention. i love fitting into smaller clothes. at my heaviest i was a size 16 , now i am down to a size 10 and hope to get to at least a 6 or 8.
my biggest worry is that i have lost all self control that i had had last summer. i need to learn to say no to sweets and snacks. i can eat small meals but snacking is my low point. i try to eat healthy , i eat yogurt and fruit but lately ive been snacking on nuts a lot which are very high in fats and every night i have been eating some type of dessert without spitting it out. im trying to drink as much water as i can but often find myself feeling bloated afterward and not as light as i used to. i hate being a yo yo dieter. school starts in a week and i am hoping to lose the 7 pounds by then. i think i can do it if i fast or eat very little.
can anyone help me. what do i eat around my family and friends, when all they do is eat and don't care about their weight. what do i do when i am tempted but dont want to? thank you all so much. my aim sn is- magoo xo
