wow! sounds just like me. one of my best friends is the same two-faced girl your describing. but its real bad. she does it to me too, and then she calls me w/o saying sry, and talks as if nothing happened. i totally get how you feel. And, i thought i was fat too, but then i got into swimming, and lost about 20 pounds last summer. i became involved in camps for soccer, v-ball, bball, and swimming, and now i look great! but looks arn't what matters. its how you feel. i felt so great about the way i looked at the end of last summer, i bought my first ever 2-piece bathing suite! and hunn, swimming is awsome. you meet so many people, make so many great friends (guys 2!!) and it is the best sport for you. when you swim, you sweat, and sweating makes you lose weight. so try it out! and when you say your friands are slipping away, do you mean, your less interested in them, or they ditched you? cuz let me tell you a story:
last summer, i was very involved with my swimming, and always asked my BFF to come to one of my meets, or to my pool. But every time i asked her, she said she was busy. i knew she was lying, but i thought she might have a good reason. but a few days after her b-day, i found that i wasn't invited to the party. i felt crushed! then when i came back from vaca, she called and told me i wasn't her friend anymore. i mean how rude is that? so then i had to go into jr. high (6th grade) not having any friends. cuz w/ my old BFF, went all my other friends! nothing could have been worse. but when i got w/ another groupof friends, i loved it! i met new people, and i had some new i'll call it senery! so try that 2!!
i hope i have been of some help! good luck, send me an e-mail email removed and tell me how it works out!
remember, your not defeated until you admit to yourself you are!
always and 4evr~
