Bless your heart. Reading your post brought back so many thoughts and memories myself.
I won't get into the debate of who has the most stress, because I do feel that nursing is a calling. It doesn't matter what unit you work there are those patients, patient families, doctors, co-workers, who leave imprints on our lives good and bad. I remember working med-surg and a woman, older woman who refused everything, even IV fluids, and how I struggled with that . But finally came to the conclusion that it was her right. That was really before the Advance Directives push.
Speaking of which, I agree 100% that everyone needs to have a living will. Not just have one documented, but talk about it to everyone. Give everyone copies. I have seen many cases that despite of the patient's wishes even with a living will or Advance directive, those wishes are over-ruled because there is one family member will swear the opposite.
I hadn't thought of the link between being a nurse and a mom = caregiver strain, but it does make sense. I do remember coming home physically, mentally and emotionally exhausted. And you are right that few understand. I think that's one reason why it's so important to be friends with your co-workers. Just this last year I've been scanning and organizing all my pictures and it was heart warming to see how often we got together.
I think how having children affected me was knowing all the what if's. Our 21 year old was a chronic ear infection kid and had to have 3 sets of tubs. Long story and I'd do things different now, but. . . I realize the surgery itself was/is routine but what I kept telling my husband is one little mistake at the hands of the surgeon or anesthesiologist and things would never be the same.
Reading your post and feeling your heart and frustration, is it any wonder there is a high degree of burnout? But the beauty of nursing as opposed to many other professions is that there are many ways to turn.
I worked in a large hospital 13 years in a variety of positions and did finally move on to a pulmonologists office which I loved! Except for a co-worker. That that's another story. In the office we did pharmaceutical clinical trials which I continued doing as a contractor. I also did some time in the legal industry as a nurse analyst. In each area, I found out things I really didn't want to know and probably shouldn't have known which changed my views on many things. But I love nursing and I miss working clinically. And I appreciate you and others who are working 'in the trenches' so to speak. You my dear are doing God's work!
