In the context of our convo, it is the "worst" for someone else to be jealous of you. As in if someone's sad, you can make them happy. You can boost their confidence - but it's really hard to remove their anger at their self.

I've been having problems at work and it's likely that this is due to their jealousy and, as you've said - self-worth. I have what they perceive they can't have, and that makes them very angry at themselves which they take out on me as the source of that anger at their self. Offering to help them won't work, as that's (to them) another instance of them failing and me succeeding. So yeah, difficult to deal with in others.
