Fics that genuinely fucked you up

Not good fics or popular fics, but the fics that left you staring at nothing once you're done, because damn, that really was something

My personal examples (spoilers for my reactions)

A gift of wings: hiccup becomes a dragon, covers literally everything and more of the animated series

>!I have genuinely never felt more empty than when I finished this story!<

Laughing at Tragedy: Micheal becomes Lolbit, covers most games and a few books

>!The way this fic ends is capital F Final, leaving no room for speculation or spinoffs. Everyone died. The end.!<​

Background Pony: Lyra Heartstrings cannot be remembered, and does everything physically and magically possible to change this

!This fucked me up in a different way, because **there is no good ending**. Either she loses all the experiences she had while being a ghost, which stretches over a year, or she gives up everything. She chooses a third, somehow worse option, where not only is she still a nobody, but she doesn't like music anymore *and* is hemorrhaging what little memory she has left, and dies homeless and amnesiac, completely forgotten by the world!<
