The presence of the term "gaslighting" in the comment you are replying to implies that this might be a situation involving narcissism. It's all very well, in a pop psych way, to tell someone "be more zen", but there is little useful overlap between that advice and the course of action that is usually recommended for people dealing with a serious narcissist (to get away from them any way you can).

I don't think you're helping by bringing positive pop psychology and generic consumer zen "mastery" to what is effectively a borderline clinical mental health situation. Narcissism and gaslighting (whatever the actual situation described in the previous comment) are way beyond what can be smoothed away with equanimity and a good attitude. It's unhelpful and a bit condescending to suggest otherwise.

The above situation seems to happen at work, and it's unusual for people with personality disorders to simultaneously have major breaks with reality at work and be undiagnosed long-term. It's odd that it's the first interpretation you are choosing to address (by calling somebody else condescending to boot), although yes, the proper reaction to people with issues that severe is backing away slowly, so it's worth being said to cover all the bases.

Gaslighting doesn't necessarily imply narcissism - it applies any time someone persistently attacks another person's confidence in their own view of reality (starting with just contesting their recollections, moving on to actively messing with their environment).

I was thinking - don't make it your mission to prove a jerk is wrong, don't engage.
