High school anxiety

Ok so I’m about to start my freshman year of high school, and I’m actually super nervous. You know how people always say join a sport so you know people, weellll that plan kinda backfired on me. I tried dance but I’m going to like a catholic college preparatory school so they have super high standards so I didn’t make the team. And I did have experience and a lot of it too but ig not enough for them. Then I was gonna do color guard but I missed tryouts, then my plan was to do volleyball even tho I really didn’t want to do it. And I missed tryouts for that too. I’m super scared cuz I’m afraid I’ll end up being a loner, I mean all the people going there are either old friends who ended up being fake for people that I just didn’t really get close too. I mean I’ve had a lot of guy friends come my way but Idk. I’m in drama if that helps. I’m just scared that I’ll be a nobody, at least that’s what my mom says. I’ve never really just been a sorts person, I like doing activities out of school. Amy advice on wat to do? I mean I’m open to options.
