Of course she would xD
Cool. We can throw that in then

Just for the sake of ease, I've been doing a little research on PTSD and treatments, so I can share some of the stuff I've found.

Basically, the only medications for it are SSRIs (selective serotonin reuptake inhibitors), which obviously wouldn't have existed in this time period. Most people use coping mechanisms to deal with it instead. The most common (and unhealthiest) is substance abuse. A lot of people with PTSD can resort to excessive drinking or drug use to escape from the trauma (I actually imagine this is what Eldon would recommend, since it would have proven to be an effective "medicine" in the knights he's treated before). Crow would definitely be hesitant to try it though, since to him, being out of control isn't much better than dealing with nightmares.

Other coping mechanisms that work for different people are meditation, aromatherapy, breathing exercises (when triggered), and physical activity. I could see the latter two working for Crow, since he's usually at his happiest when he's working his body, and breathing exercises would help him calm down if he has a flashback when he gets triggered by the sight/smell of blood.
