Hey there.
Don't worry. High school is unpredictable in so many ways, you'll be surprised. Don't worry and don't question yourself.
Eventually you will find people who will love it when you're there. I used to feel that way and suddenly, it changed. Don't bother too much.
Meanwhile, focus on making acquaintances, people who you can chit chat with so you don't feel lonely at school. Don't ever chase after anyone too much.
While you're at home, try to find other things to occupy yourself so that you don't think about this and hurt your own feelings in the process.
Something good is around the corner, Im sure
