After many years of acute Med/Surg nursing, I was offered a job as a hemodialysis nurse in the acute setting. Basically, I go to various local hospitals and give dialysis treatments to patients with acute renal failure or those with chronic renal failure who are hospitalized for something else but still need their treatments while hospitalized. I realize that this isn't clinic nursing, but it was a much needed change and for the first time in many, many years, I actually love my job and want to go to work. This is huge for me, because I was the acute nurse who hated my job and literally prayed to be called off every single shift.
One of the things that has alleviated a lot of the stress for me is that now I only have to deal with nephrologists, not all of the patient's physicians. When a crabby doc shows up during a treatment and demands to know who the patient's nurse is, I can say "Oh, I'm the dialysis nurse, but I can find him/her for you!" For anyone here who has worked Med/Surg for any amount of time, you can probably relate to how good that feels!
Best of luck to you! Life is way too short to do something that you hate and that stresses you out this much. Clinic nursing might be the answer for you, or perhaps hospice, home health, dialysis, or some other type of nursing. The beauty of nursing is that we have so many options and therefore are never really "stuck" doing something that we hate.
