I hate being fat

I truly hate being fat. I'm 160, 5'4. I want to be able to run even a quarter mile without being winded. I want to be able to have a girlfriend. I want to not be endlessly mocked for being fat. No matter what I do, it seems like I'm still fat. I've tried eating healthier, eating less, moving more, doing more cardio and yet nothing changes. I really don't know what to do. I desperately want a girlfriend, someone that I am able to love and yet nobody likes me because I am fat.
