Beating Yourself Up

How many of us are like this? We save a life but instead of feeling good about ourselves, we beat ourselves up over what we did wrong, could have done better, or should have done instead?

I spent my entire first year as a nurse lying awake at night doing just this- but that was a while ago, and now mostly I just go to work and do my job and come home feeling pretty good about my work.

But sometimes, even if the outcome was good and all ended well, I question every little thing and chastise myself for how I "should have" done this or that.

I have a feeling I'm not alone here.
