Overweight and alone

I'm 16, 5'3 and 280 lbs. I just move to a new town and I don't have any friends here. I've never had a boyfriend and I think it's because of my weight. I've had plenty of friends that are boys but it never goes past just friends. I feel like I'm going to be alone forever less I find a way to lose weight. I work out often and eat healthy when I can. Is there anything I can do?
