I'm really sorry to hear you are having trouble at school, but i think i can help you
The best thing you can do is ignore the bullies when they call you names and don't show that you are upset
If you ignore them, they will get bored and leave you alone
You can also join some after-school clubs
This way, you'll meet people with the same interests as you and make new friend
I really hope my advice help and everything gets better soon
