Hello there mate, sorry to here that you're through all of this stress.
Bullying is not the victims fault but rather the culprits. It's not something we can really avoid.. People want attention and all of that, that's why most people tend to bully and do other stuff. I would suggest y'all to just act like you guys are friends... well... friends in a relationship (I have no idea what I'm saying) but you get the idea right? just act like you guys are friends and there's nothing "special" between y'all.. I think things will be alright then, by the way don't get stressed over the summer, we're suppose to enjoy it. And they'll probably forget about it by the time school reopens.. That's the only advice I can give
Take care of your self mate!
