OMG I hate my weight help!!!

In the 100s and I'm the 2nd tallest in class. when I eat I always feel guilty and try to vomit but nothing happens, I eat 공식 만찬, 저녁 식사 then do it sometimes I'll skip all my meals 또는 I eat 1 meal a 일 witch is every 일 lately! I haven't worn a bikini in 2 years to shy and my belly goes right in like 카레 and my nan, mum, freinds say I'm not fat stop siting, I'm like so shy to tell my mum for help only freinds but elusive I run on the spot like in my spare time, push ups, yoga, dance and school basket ball and this is becoming a addiction HELP!!
