I'm sorry to hear about your situation, bullies are pathetic and usually have their own issues as to why they lash out on others - but that's no excuse for their behaviour. I was in a similar situation and left my friend group, but it honestly wasn't that bad and I found better people, you can too. At first you'll feel a wave of emotions but gradually you will feel better, this situation is temporary and won't last forever. Hopefully you'll find new and better friends by joining clubs or spending time in other parts of the school. You're not really at a loss here, rather those so called 'friends' are, if they were ever true friends they would have supported you and helped ease the situation in your group rather than making it worse. You don't necessarily have to be enemies, you can just avoid each other and cut contact, you have so much more to life than these weirdo toxic people - don't be afraid to stand up for yourself.
Don't be afraid when you've done nothing wrong
