To be fair, it is different because it impairs perception.

There's good evidence that depressed people are better at detecting simple sadness in others, and there's some evidence that depressed people are better at correctly predicting when things will have neutral or negative outcomes, but beyond that it gets a lot hazier, because depression messes with empathy, tends to project itself onto the world, and because non-depressed people will mirror your sadness when talking to you, etc. etc.

(I'm not talking about depression, though, but burnout, which is its own animal.)
