Let me tell you guys some backstory on myself first

I (26F) have been bullied since I was a kid, it all started with a group of friends I used to sit with, I’ll admit, I was a bit of a cringey kid to them but after a while I stopped, yet they didn’t, for years I was targeted and made the scapegoat/punching bag to the point even the rest of our class would join in and people I considered my friends would make fun of me

One day the entire group left early so I had no one to sit with, not wanting to sit alone I looked around for any available seats and sat with a group of boys who I became good friends with, after a month I started acting like my old cringey self again to which, Again, I was picked on with my old friend group even chiming in and telling stories which would make the whole class laugh at me, the teacher wouldn’t do anything just tell them to be quiet and keep teaching

This went on until I eventually got asked to fight by one of the girls from my old group, we fought and I won, the old group left me alone and the new group started to respect me a bit more and actually told me why they even picked on me in the first place, we started to be good friends after that and even left on pretty good terms, it’s been years since then but I haven’t been able to shake the fear that I’m going to slip up and become a pariah for the rest of my life, high school was lonely and quiet for me but I got good grades, barely had friends and was always on my own

Fast forward to a few months ago I’ve recently finished up college and got a job at a Foot locker back home, I know I might get criticized for this but I’m just tired from college and my parents were fine with me taking a gap year, so before finding work in my field I decided to get a much calmer job to make some money and get on my feet, that’s when I met Jason, Jason has been a pretty chill friend and one I don’t talk to much but the few interactions we’ve had were overall positive, Jason introduced me to his friend group and we began hanging out, but there’s just one problem, let’s call him Peter,

Peter has been nothing but an asshole to me, it all started when I accidentally placed a few pair of pants next to shirts to which he started getting mad and saying I was “fucking everything up for him” because our boss would complain about my mixups and Peter would instantly throw me under the bus, anyways, since then he makes fun of me all the time, has said to my face that he hates me and has even called me slurs to my face but stays completely quiet if a girl passes by then continues whenever they’re out of earshot, if it’s not that then he deliberately makes fun of me when a girl is nearby to get a laugh out of them, recently I’ve had it and just told him to fuck off, now everyone in our friend group has basically gone radio silent on me after saying I “overreacted”, that I’m too sensitive and it was all a joke

But I swear I could just feel my middle school experience being repeated everytime Peter opened his mouth and spat some more hurtful words and slurs at me, but I don’t know anymore, I’ve never really been able to tell what people mean when they say things to me and it’s always been a problem since I can’t tell if he actually was joking or not because now the whole group has turned their backs on me

Some advice would be appreciated, same with criticism, I want to change if I’m genuinely doing something wrong
