I think it doesn’t compel me in the the same way other forms of whump do, because there’s no one you can blame. There’s no one you can fight. It’s just a random, miserable thing that happens to you with no greater point or purpose.

I can definitely see why that would make it even more compelling to some people, but for me half of the fun of whump is the fucked up dynamics between the characters and how they got there, and where they will go from there.

I think the only way I would end up writing illness whump would be in a situation where disease was personified in some way and could interact as an antagonist.
