New school anxiety

Lauryn🕷

Hey guys! So let me start by explaining a couple things.

The elementary school I went to fed into one major middle school (there's another middle school but almost everyone goes to the one middle school, let's call it East Middle School) So after the end of my 8th grade year I'd known everyone since kindergarten and everyone in the school knew everyone. So there's one main highschool that East feeds into (let's call it Texas Highschool)

Anyway, I'm a freshman this year going to a different highschool than all my friends. The only person I know at the highschool I go to is my older brother. I had multiple anxiety attacks before school even started just thinking about not knowing anyone. So I get to school on the first day and start to freak out because no one seems nice and I hadn't made any friends by lunch. I had another anxiety attack on my way to lunch because I didn't know who I was going to sit with. I ended up waiting in line to get my ID picture taken (I didn't even get halfway through the line anyway) so the first day of the second week of school is tomorrow and idk what I'm going to do. I'm freaking out just thinking about it. Does anyone know what I can do to help make friends so I'm not eating in the library the whole year?
