A little low on compassion

I have been working quite a bit in ICU lately which is a good thing; however, they have been VERY short on nurses lately and that has become taxing. Part of my growing frustration is that I'm not the same kind of nurse I used to be, I'm not sure if this is due to menopause or chemo brain. In emergencies, I used to be pretty good at multi-tasking and I could store labs/drug amounts/orders in my head until I had a chance to write them all down. Now...not so much and it is really shaking my confidence! Sometimes I really wonder if I belong in ICU anymore. I suppose it will be an adjustment process before I find a system that works well. It is definitely humbling!
There is a dark side to nursing that we (nurses) often talk about amongst ourselves and I'm a bit conflicted about sharing it to others, but the truth is I need prayer. It's no surprise that as the world continues to push God out there is an increase in self destruction. I'm seeing a disturbing trend in the patient population of ICU, they are young individuals whose destructive coping skills are literally killing them. For the most part, I take care of two patients at a time and I can honestly say that at least one of my patients is in the ICU from drugs, alcohol, or both. I'm rapidly growing tired of trying to save someone who is determined to kill themselves. Sometimes I feel like I'm wasting my time and efforts, we patch up these young people only to have them come back in a worse condition. I'm tired of watching our tax dollars go towards alcoholics and drug addicts who have no intention of trying to become sober. Life is truly a gift and I'm tired of watching so many throw theirs away while others are desperately trying to fight. I'm running dangerously low on compassion for these people and I know that is the wrong attitude. God loves these individuals and they deserve a compassionate nurse, not a hardened, sarcastic nurse. I need prayer for compassion, that's the simple truth.
