How do you make yourself look pretty when you're honestly not?

I'm fourteen and goin into highschool. Ive been bullied a lot at middle school, mainly by guys. i have a reputation at my school; ugly snd flat chested. i feel really ugly all the time. i dont think theres one good thing about me and i dont even let my own family see me without makeup because when i even see myself without it its hard not to cry. im tired of feelin and lookin this way and i need any makeup or skin tricks to help me look prettier in high school. im tired of my reputation, please help me.
