I don’t know what to do

I’m 13 (14 in 13 days🎉) I’m in year 9 going into year 10, I have no friends tbh, I sit in the bathroom at break and dinner so I don’t just awkwardly stand there by myself, I have people I talk to but non that would consider me as their friend, I used to hang around with a group of people but I was the laughing stock on the group, they would call me names and push me and trip me as a joke but it got to a point where it wasn’t funny anymore and it began to upset me, I tired to ignore it but it got worse. And also recently a girl started on me and called me a rat and stuff cause she told the entire changing room who her boyfriend was and when someone she didn’t like found out she had a go at me because she didn’t want her to know (she told EVERYONE in the changing room) I also have a boyfriend and I love him so much, but I just wish I had friends, Ik it sounds desperate but If anyone around my age wants to be friends my insta is @emmaboyllan ❤️
