girl no. that girl doesn't owe anyone entertainment. if she's having a hard time and wants to step back for a while, that's completely fine. nobody can force her to do anything she doesn't want to.
plus, if they're doing this to her, they might do the same to you and the others when you're overwhelmed and need a break. i think you should talk to the rest of the group and get their opinion on this, then approach those two with a decent conversation and if that backfires, I guess it'll be your turn to get ugly lol
i hope your friend is doing better and i hope she knows she's allowed to feel the way she is right now❤️
