Why am I always called toxic?

Anonymous
I am known as the butt of the joke in my class. They all love me and I love them but everytime I make a mistake or slightly get annoyed or just do anything they start laughing and bring it up even tho it was months ago. I'm not that person that loves too much jokes. And everytime I say that it's not funny or do the same back they say that I should stop taking everything personally blah blah. I love them and I know they don't hate me, but I'm just not that joke friend and often get annoyed by their jokes. Oh and let's not forget the sentence 'So toxic' Maybe I do take things personally but that's how it is and sometimes it's tiring. Does anyone get what I mean?
