My best friend

Please help ladies idk what to do anymore, I’ve been BFF with my friend for 6 years now but recently we’ve gotten so close and she’s always mad or if we go out for drinks I feel like I’m stepping on eggshells. Any little thing can ruin her whole mood, sadly I’m starting to feel like I should just cut her off or back off because there are times she’ll text me complaining about everyone she works with.. just so negative and I feel like it affects me. Always hearing negative things.

This past weekend we went for drinks with college friends (who she also knows) and two of my friends had mentioned (after she left) “omg you really can’t joke with her” “she kills the vibe, we’re all trying to have a good time”

I just told them that’s how she is but they can let her know how they feel because I don’t feel comfortable talking about her.

I’m everywhere because I love her to death

I guess

How would you go about this?

I’m scared to even bring this up because how sensitive she is.

But I guess I want to do that before cutting her completely off.

Any advice?
