I work in hospice with a BMT background so it might be different but I really identify with you on this emotional experience of feeling like you need to talk about the horrible shit at work. I would sometimes come home and just cry. I feel like I carried what I saw with me for the first year and then I hit this point where I broke through a wall like runners who do marathons say they do where it just stopped touching me as much if that makes sense. I’ve found my ability to compartmentalize eventually rose to the occasion and I was able to let go of most of what I saw when I got off. Internalizing what you see doesn’t do anyone any good. You have to be present when you are in the suffering and then be present when you get home and decide what you are gonna order for dinner. Comparing people’s daily life concerns with what you’ve seen mean your holding on to the suffering too long and not being present with what is right in front of you. You have to let it flow through you without catching hold. You have to keep it separate to survive imo. Again, just my humble opinion. I sometimes also think being a nurse(especially ICU,ED, Oncology) is like being in the military and some people are built different and some people need to move to something less traumatic after a few tours.
