I want to cut off my friends over a video game
Why would you do something like that?
Why do they have to gang up on me all the time
What do you mean? Either way, I don't see any reason to let a video game affect your friendship. It doesn't seem to be worth it to me. Don't take video games so seriously.
They don't deserve to be my friend after they let me die in the game.
sometimes mistakes are made in videogames. You need to be more mature about dying in one or else you won't have any friends at all.
