Why are the ppl I work with such a giant pain?

They are so negative! All they ever want to spend time discussing is how unhappy they are or how much they don’t like this person or the way that person does a particular thing. They have no idea of how to just leave things be. I’m constantly having to ask them, “ok, but how does that really affect you?”. It’s gotten to the point that they ignore me bc they’d rather keep their pity party than realize that none of the things they panic about actually matter.
