Sounds like some people I stopped being friends with from work last year. Everyone else is always the problem. Eventually they had a problem with me and their issues weren’t even valid.

You can’t win with these kind of people. Your best option is to avoid them as much as possible and let them inevitably bring themselves down. Keep everything work related and stop doing anything extra for them.

Sounds like that’s already in progress. It sucks. It sounds like you’ve been really kind and tried to stand up for them. Maybe they have some underlying issues, but that’s not your concern. You should be protecting yourself.
