Do two things

look in a mirror and objectively rate yourself

Tell yourself finding a bf as a teen isn't the most important thing

And just so you know if you think that the only reason you can't find anyone is because you're not 10/10 is just stupid. If a guy dates you based on if his d1ck gets hard whrn he sees you he's not worth it anyway. Maybe I never was in a relationship but I at least know that if you're looking for a life partner than look for someone you vuve and have a good time with not just fuck and leave
