I've been in that situation, too. :/
Anyway, here's some advice from my experiece:
-Bullies will continue to 'control' you until you show them they aren't causing any harm, so try not to look upset around them.
-You could fake being outgoing(Fake it, till you make it,right?c:) , they're most likely going to only target shy people.<-Belive me, I know it's hard, but you can do it! I did!
-You could ask your parents(Or someone close) for help.(And if it's physical bullying, call the police!)
And for the online bullying:
-You could block them(If possible)
-Create a new account(If that's your only choice.)
-Ignore them
-Report them
I hope that helps! :)

I.....I.....-hugs- I wish the most absolute best for you. -sallutes- Be strong soldier, the road will be rough but when you reach your goal you'll look back and say "I went through it and came out stronger than before." you will go through it and come out stronger. Also, tell someone really close or just report them. They don't need to mess up your awesomeness! They messed up theirs, why should they mess up yours? They have no right to do that.
