There's another version of this list where fics are organized by diagnosis. I recently had to break it into two parts because the original file exceeded the size limit.

Sick!Fics by Diagnosis A-L (http://community.livejournal.com/sick_wilson/41139.html#cutid1)

Sick!Fics by Diagnosis M-Z (http://community.livejournal.com/sick_wilson/41357.html#cutid1)

Mpreg stories are not included on any of the lists.
