How to handle insecure people at work

I have these 2 collegues.

1 is getting passive-aggressive when feeling hurt (usually for pretty neutral things I say, they are turning it into something negative and change the narrative)

2 a person who gets offended easily and then vents with other people from the group about it (this person is an enabler I think and even I vented with her before but regret it massively)

Like how do I manage to be in this group. it feels like a minefield to me somehow and I have no one else to rely one basically other than them.
