I don't know if you've notice... paradise is chubby. Even at my age dude's don't want a chubby girl no matter how pretty her face is.
Well keep ya head up, I think you look cute .
If it's just about being chubby, then step your fitness game up. Nothing wrong with being a bit chubby, but going to the gym makes you feel good not just physically, but spiritually/emotionally as well . That's one of the best ways to boost esteem.
