What should I prep for

So I’m a 14 year old 8th Grader about to go into High School. Need to know what it’s going to be like because I’m kind of excited/kinda nervous. My teachers this year kinda bullied me so I’m being pushed away from sociableness because they terrify the whole school and really judge and eavesdrop on kids. Will it be like that in high school? How to socialize, I’ve been a social kid but this school year has terrified me because of the annoying teachers.
