Nervous about school

I’ve been on school break for about a month now and it finally reopens on Monday which is like 2 days away and I’m feeling pretty uneasy about it. Originally I thought that I was moving schools since I’d been applying for a couple of boarding schools but I didn’t get accepted into any (maybe this is a good thing since I don’t think I would’ve been able to keep up with the routine anyway) so I’m just staying at my current school. About like a month or 2 months ago we got to pick which stream we were gonna be in but I didn’t think to much because as I said earlier I thought I was moving but I didn’t but anyways I picked the art stream because the other was the science stream which is hard and I have no interest in. However the downside for this is that being in the art stream gives me less opportunities when I apply for college and stuff. But I’m not worrying about that rn, what I’m worried about is the fact I know all of the kids that are gonna be in my class and one of them is absolutely INSUFFERABLE and bullies me sometimes which I obviously dislike. Two new kids are joining my year group but I doubt I’ll befriend either of them. One is a guy that’s joining my class and the other is a girl joining the science stream. Also another bad thing I’m scared about is the fact the only person I was ever friends with in this entire school is gonna be in the other class so we’ll be separated, I’m mainly worried of this since I usually ask her about school stuff whenever I’m absent or unsure about something. I hope I figure something out soon cuz if not I’m not sure how I’ll cope with things. The other day my dad sent an email to a hospital asking if I’m able to get a therapist of some sort but my dad hasn’t updated anything about it but I hope I get an appointment soon because I really REALLY need it. I can’t keep venting out everything online or in a journal, I need someone to listen
