Help me

Honestly, I don't know what to do at this point. I have a great life plenty of friends. I'm in lots of school activities and have a good house and every thing that i need. Don't get me wrong, even though my family isn't the wealthiest i have it pretty good and i enjoy every bit of my life.... except one part, myself. I don't mean that i hate my personality or my face or anything i just hate my body so much. i'm 5'3 and weigh 163 pounds and i don't know what to do with myself. My best friend is super pretty and gets a lot of guys but i get like none. I can never find clothes i feel confident in and i constantly feel like a fat lard. i hate the way i look and i've even tried fasting, dieting, and was almost about to starve myself. I don't know what to do anymore and I can't take it. I hate my body I freakin hate it!! should i just starve myself or what should i do???? I'm only 13 so i can't get a personal trainer or anything like that and i'm just at a loss. I feel so lost and self conscious about EVERYTHING i wear, every picture i'm in, everything and anything that has to do with my body, i'm worried about. idek anymore.
