I doubt it, that premise is garbage. That sounds like some hurt/comfort or plain Luna torture fic, which I wouldn't read anyway. I generally discard "on the moon" banishment fics because they're cheap edge without payoff.
The closest one is I Watch the Moon, it's an "on the moon" fic which explores Luna having depression/being bipolar from her banishment, but it's not trying to be extreme. There are much better fics, like Apotheosis, where Twilight helps Luna rebuild her own psyche, which is much more in line with what Luna should be able to do.
