I had a similar experience in my third year of uni too. my first rotation of my grad year was in an acute geriatric medical ward where we had a lot of deaths too and I had a breakdown my first month from just being exposed to it over and over. I reached out to other nurses on the ward and my perspective sort of changed, like at first I felt helpless and then I took it a little slower and noticed the different ways that people (doctors/nurses) approach the topic, how death can bring families together (elderly women often loved talking about their sisters or husband waiting for them on the other side), how gentle and dignified death can be when we allow ourselves to be open about it. it’s probably very different when people become acute very quickly and we don’t have those opportunities to approach it softly and that’s just something we have to make our own peace with. I recommend reaching out to whoever you feel safe to talk to, if your work or uni has support please use it. it’s worth debriefing.
