The only advice I can maybe give, if you feel like you have a strong enough center that would be able to recover if it weren't constantly forced to take in water, is step back in any ways you can without too much of a loss and take that time to yourself - to replenish, recharge, and get some space to do what you want to do.
As far as trying to 'get even' the scale is all wrong. I've had a similarly difficult go of it and when I think of it - there's no school I could have gone to where things would have been different (at best a dice roll, maybe at random 1 out of 10 places would have on some long odds landed me friends who would have both helped protect and cultivate me earlier - took until mid to late high school before that started happening). You're looking at society-wide behaviors, society-wide proclivities, it's really much more like minority persecution than bullying in the normal sense.
The challenge is accepting that the world is what it is, that people are what they are, then looking within and figuring out which parts of what you've wanted out of life can be cultivated in private, on your own selective time, maybe with a few friends, but whatever the case is it's likely not going to be easy in terms of everything else and you need to establish an active reservoir somewhere in your life to replenish/recharge yourself.
