Need advice for teambuilding rejection
So I'm gonna have a team building soon, but i do not want to go while probably every of my colleagues will go. I tried to tell them that i won't go but they always interrupts me, saying "oh you will enjoy our time together" and "you should step out of your comfort zone" things like this. My problem is, I'm antisocial and shy, always trying to avoid conflicts but i really don't want to go. They asked me if i hate them or something. No i do not hate them, but i don't want to hang out with them after work, going to drinking. These things make me anxious, being in a pub, around a lot of people and staying out for the whole night. I really need some advice please! How can i reject them in a nice way? I wanna explain to them that im not that kind of person who likes to do these things but at the same time i don't wanna look like a person who never goes anywhere (which is not true, because as an introvert i still have friends and like to hang out with them).
