im tired of being lonely

i am a 21 year old guy and i need help. i am not very attractive, i am 5’7, my face is asymmetrical. i also look young for my age. most people think i am 16-17. i work out and have a somewhat nice body. i have no idea how to find a gf. i can’t even talk to girls because i believe i’m too ugly too talk to them and i don’t want to waste their time or offend them. i don’t have any friends either so i don’t have any social circle. i work at a mall and i sometimes have girls who are interested in me but most of them are in high school. i am friendly with all of my co-workers but i cannot become friends with them because they are all indian exchange students and they don’t want to hangout with someone who doesn’t speak their language. i try to become friends with other people who work in the mall but most of them don’t want to because either i look too young or im too ugly and they don’t want to be friends with someone who is as ugly as i am. i don’t know what to do. im so tired of being lonely. everyday i see people out with their friends or their girlfriend and it hurts my heart so much because i can’t experience that. i don’t know what to do
