I actually do not like speaking happy topics. I like speaking with depressed and melancholic people. This is a type of negativity but not the type that is bullying. And yes, in case of a bullying I would feel negative. But during a conversation with a depressed or a melancholic person I feel so close. I understand easily. Because I am melancholic and I accepted it. And no, I am not changing it.

Yes.Sometimes I even feel negative just being with them even when I don't talk to them at all.

i walked into my office yesterday and i felt the negativity immediately. i sat by myself and did not interact with anyone. it was awful

All the time. Probably because I'm HSP. (highly sensitive person).

Yup, that's why I do my best to avoid them.

No

Sometimes.

Yes I have.

I tend to avoid these types of people where possible.

Yes they suck the joy right out of you.

That's bound to happen. It's easier for people to feel like shit than feel happy. At least for most people. That's why it is best to avoid the negative people as much as possible.
