Important enough to reblog on the main, to give y'all context into what health pros see and deal with, especially (but certainly not exclusively) ER/EMS/ICU/critical care people, who tend to end up in fiction disproportionately.
Look, here's the thing: as a rough and general process, health professionals go through a number of stages of development in our careers.
Most of us start off with an Overabundance of Empathy.
Then, as we experience more and more traumatic things that we can't actually stop, we get Shocked, we Hurt, we Cry, we feel Desperately Overwhelmed. And then we Distance and Make Jokes, and become Kind of a Dick. It's a natural reaction to feeling constantly assaulted by other people's need - while having deep and unmet needs of our own. (We also feel desperately incompetent a lot of the time and cover it up with bravado, especially early in the career.)
And then, if we really try hard and have the right support, we come back to a place of Empathy with Context. To accepting that not everything ends well, and at the same time, that we don't have to be callous - that we can engage in empathy even with the risk of loss and trauma because we have experience handling that trauma and accepting that we can only fix what we can fix - that's not everything.
So if you're writing a character in health care, ask yourself - where are they on that spectrum? What's their emotional development? How badly do they need to push people/things/experiences away to not feel hunted by other peoples' suffering - or have they come to acceptance with it?
To the OP: this is a beautiful poem, and resonates hard even after the end of a health career, and I hope you don't mind me adding this to help writers more accurately write about health practitioners of all stripes.
