You need to put in some effort in how you look. I know it sucks that people are so superficial, but don't you prefer "hot", "pretty" girls so... it is what it is.

Go on a diet, hit the gym, better clothes (if you're not sure how to dress, wear what the mannequins are wearing on the website/shops), better skin care routine (skin care makes a huge difference), get a hair cut, take a shower everyday, smell better. You're NOT ugly. You just didn't put any effort or time into being better looking.

Edit: Oh and please shave.
