feeling ... fat.

well im a 15 year old girl and last time i weighed myself i was 250 lbs.. i know im over weight but i dont know where to start to lose it. my parents are really strapped for money.. i dont know im just feeling really disappointed in myself. i was trying to find a bra for myself and i looked in the mirror and all over my stomach and sides i had stretch marks and all i wanted to do was cry - i know its stupid and i know its probably PMS. But last week i was dignosed of having PCOS and one of my friends told me its hard to loose weight. that and... i hate my body hair.. like theres hairs on my stomach. and i know i'm feelingb insecure.. what doesn't help is i might be meeting up with my crush to hangout for the first time since we started talking but we've met brifely.. i dont know i just feel ashamed of myself.. and i don't want him to see me because of how i look.. i just wanna cry and i feel ridiculously stupid...
