I FEEL FAT!!!!!!!!!!!!!!!!!!!!!!!!!?

Well I am a 14 year old girl who has issues with weight, I'm 5 foot 6, I honestly didn't think I weighed 142 pounds but seeing my self weighing that much made me sad, i've been skipping breakfast and lunch usually every day, and whenever we sit and watch tv I do tummy excersizes. I feel hopeless and it sux seeing all the fricking 80 pound b!tchez walk around wearing size nothing jeans. Also, if I loose weight will my t!ts get smaller 2 cause there huge and annoying.
