how do i get a boyfriend when i look the way i am?

i’m in my last year of high school and have experienced being rejected than rejections. i’m the DUFF in my friend group, not to mention i’m brown and short. i’ve tried to become more confident, i’ve tried to lose weight, ive tried to put myself out there, and no one wants to look my way. i have friends who have men lining up for them, but no man wants to look at me except those creepy guys you see at night. i know my mindset right now sounds like a debby downer, but these thoughts only come up once a blue moon, and it’s really hitting now that i realize im graduating with no experience. what do i do?
