If you think of your self as not attractive try something I've heard other people do, and im trying myself, look at your self in the mirror and find something you like about your self. I've heard a lot of people say there eyes so,possibly you like your eyes, then just find a way to "show them off" and think of yourself as good looking because of them. Also I get the feeling of wanting to feel wanted in that way, I know that feeling, just try to stay confident and people will see that you're confident about your self and possibly, like you more, but if your always depressed or don't like your self then people will see it as a bad time to approach you and well yeah... but I bet in the future if you keep your head up, there a great things that lye ahead. Good luck and I hope you can try to appreciate yourself some more. Stay confident in yourself.
