How good is your school academically?
If you got expelled, how good academically is the school that you'd be most likely to be moved to? And is it further from where you live? And if so what additional travel time would you be looking at in the morning?
It's possible that you're in a position where you should play the system and deliberately get expelled so that you're moved to a school where the teaching is at least as good as the one you're at now and where you can make a fresh start with the bullying and hopefully not get bullied at your new school.
Also, is there any possibility you're on the autistic spectrum? Have you been professionally assessed for this?
I know pupils that have been on the autistic spectrum, but never diagnosed, that have had a much harder time at school than they should have had. It's worth checking if this is the case for you.
As a general comment; there's a lot about school that isn't fair. With a lot of the unfairness being the sort of stuff where pragmatically, it's best to shrug your shoulders and move on. With the most outstanding unfair things becoming anecdotes for you to tell for years to come.
