Did anyone else feel like today was a really weird day?

I know I'm kinda outside the age range on this chamber, as I'm only 15. I'm not incel yet but I feel like it's coming. I have a lot of anxiety and today, being the first day back, so obviously it was tough. But it felt... different. Like something went wrong. I know it's been a while since I've been in a classroom, but I'm just wondering if anyone else is having these feelings?
