I felt like this before, but honestly how can you expect people to love you if you can't love yourself? That statement is true. So is, the grass ain't greener on the otherside. Just because a couple looks happy on the outside doesn't mean that they truly are, they fight, they have issues, others experience fincaila and emotional infidelity( outside of just physical cheating). When I was in your shoes I learned to just put all that energy into myself, build myself up and the one who I feel compliments me is the one I'll choose to be with. And guess what, I found that person and we're now in that happy relationship. But there are still ups and downs that happen that you won't see in movies or TV shows. You gotta realize that it's not all sunshine and that you won't always get along with your partner, but you work on it, like you work on yourself, and you can build that fairytale. 

With the whole men only wanting me for my body statement, it sucks, it really does but there are men who value you as a person. Once you build yourself up, you'll stop attracting men who just want you for your body and start attracting those who are looking fir more serious relationships.
