What should i do with the way that i look?

I am really skinny, i wear size 0 jeans. Ihave a problem with the way i look totally i jus dont like my body. I try to eat alot but i dont put on nething. i dont wear half of my jeans cuz it fits tight n i look extra skinny. i looked at anorexic girls on the net ian i was so happy dat i had more size dan the but some girl look like methe same size. I cry alot, maybe becuz there are alot of mean ppl out there. i walk with my fren that has same size as i do but they always seem to pick on me. sometime i hate livin i dont even wanna go out. i should accept myself the way i am but ppl are always bringin me down all the time i hope i dont look anorexic. im cryin all the way writin this, u guys know of somethin that makes u gain weight. i not comfortable with myself maybe dats why ppl tease me. some ppl are blessed and others jus cursed like myself!
