Obsessions and insecurities.

Lately I think I've hit an all time low on how I view my body. I hate my small boobs. I hate how i feel less of a woman because of it. I hate how other girls judge me even tho we should all be supporting each other. I constantly compare my body with other girls bodies thinking that it isn't enough. Or damn i wish i had her...etc. any advice?just feeling extremely insecure.
