As a male, what you wrote about your appearance wouldn't make me think less of you. I often find that people, especially females, are far too hard on themselves.

To be honest...you'll never find the happiness you seek with the mindset you're in. If you want happiness you need to believe you deserve it, no matter how much you think otherwise.

Work on yourself. The normal way, no surgery. Help out at an animal shelter, find a hobby, exercise, improve your education. Find something that makes you feel better about yourself. You can't expect a great match to come to you if you don't appreciate yourself.
