Have you ever been at the receiving end of other people's negative emotions? You might have a partner who gets needlessly critical at home because they've had a bad day at work. Or a friend or colleague who keeps passing snide comments without fully expressing what's bothering them. Or a child who sulks and spreads misery all day with a curt "I don’t want to talk about it" when you try to help them.

Misery—like joy—is contagious. And while most emotions have a relatively short lifecycle—which generally makes it easier to manage other people's moods—some people insist on holding onto their negativity until the whole world knows about it. It’s not that they enjoy spreading misery; it’s often because they feel overwhelmed by their emotional surge and have no other way of dealing with it. Seeing another person suffer alongside them makes their own load lighter, and takes some of the responsibility off of them to do something about it.

No wonder, then, that such people are often at their most negative around sensitive people. With mile-high emotional receptivity antennae myself, I know how exhausting it can be to be around them. I also know that it's extremely frustrating because you feel stuck between a rock and a hard place. You stay with them and you get swept away by their emotional onslaught. You distance yourself and they become more persistent, a push-and-pull cycle that eventually leads to negative outcomes.
