A/N: William Battie's 'A Treatise on Madness' 1758, is considered the first volume on modern psychology. Psychology wasn't officially recognized as a science however, until 1879.
Attack on Titan takes place in between this time, and the psychological practices of the time were still rather barbaric in comparison to now.
It's because of this fact that I'm tweaking the narrative and giving Levi a progressive, more modern therapist. Fight me! *Doctor's notes are comprised of an assignment from Psych Class this past year*
