How do I get rid of my body image problems and build confidence?

I never thought I'd be feeling the way I am, again. I am very self-conscious about my body. And One day on this networking site, as soon as logged in a girl posted a question about skinny Vs. Curvy women. And they way she talked in the question was as if she hated smaller women. There were many people commenting and making hateful comments like: "Ruler shaped women look like 12 year old boys", "why would any man want a boyish shape woman", "any man that likes ruler shape women are gay pedophiles.", "they are aneroxic boys","skinny women are less fertile","I don't want to be hugging a man", and etc. I really hurted to see these comments, and to know that people actually feel my figure is somewhat like a man's. I don't know why people have to uplift curvy women, but in the process bring skinny women down. Yes, it is the media's fault for displaying skinny women as the ideal body. But people don't realize in reality women want a man that loves her in her body, and most men are into curvy women and down talk the skinnier ones. Hearing those comments actually made me look in the mirror, and see my body not as feminine but more masculine. Sometimes I don't feel women enough because I've heard the term "real women have curves" so much. Though many people may see my photos and clify me as an "exception to ruler shaped women", because my legs have feminine curves part of me still wants to beat myself up about it. It's like I want to feel good about myself, but I make myself think that I have no reason to feel good. How do I get rid of this feeling?
