It has nothing to do with how you look. Just like with the previous posters, it is because you are clingy and push them away. Please just stop torturing yourself and leave them alone. I know it is hard, trust me, we've all been there. But sometimes you just need to move on and find other people to hang out with. And like I said, actually try to take advice from this site, people are actually trying to help and you not changing is ,along people really mad.
