Since people have already given the same advice I would for the bully, I might weigh in on your friends. They fact they didn't seem to be willing to stick up for you against your bully, I might look at how good of friends they are and whether they're actually good friends. Losing friends is hard, especially all at once but sometimes it might be necessary for yourself. Don't jump into losing all your friends but certainly look into how good of friends they are to you besides hanging out. Good luck

Well that’s horrible.

Yeah exactly what twain said though. Stand up for yourself but do it responsibly and calmly. You can’t help sitting in bus seats but if she says shitty stuff defend yourself 

Dang, bro. I'm sorry this happened to you.

I feel like the best thing to do to a bully is simply stand up for yourself --without getting angry. Generally, bullies just want to get a rise out of you, make themselves feel better, or make themselves look better for their friends. They think it's cool.

It ain't.

If you calmly stand up for yourself, without being mean or rude, (if you are mean or rude, then you're no better than the bully.) you might upset them. They might bully you more, but keep standing up for yourself, and eventually you'll scare them off, or bore them.

But be nice, ask why they bully you, ask them to stop, etc. Be polite and kind.

That's all I got lol. Sorry for such a long comment!
