I have been single for over a year now

I’m 17. My last actual relationship ended in March 2017. that summer I fell really hard for this guy but after 2 months of being together, he just left me on read and never talked to me again. The last time I tried to pursue a real relationship, was this May. I met this one guy, but after 2 days of being around each other, I was just repulsed by him and I don’t know why.

I don’t go out a lot, people at my school are trash/ignore me, and I don’t even like hookups anymore. I can only find solace in dating older guys but wtf am I supposed to do when I want to be with this 22 year old guy from a dating app and my parents think everyone older than me is out to hurt me?

I don’t know I’m just ranting. I’m so alone.
