Work anxiety...advice appreciated

Hi everyone. I've been a nurse for over 3 years and I really like my job. I would describe myself as a type A personality and always make sure I follow hospital protocol. But, sometimes I make minor mistakes and I beat myself up over them. I try hard everyday to do everything correctly, but when I make a mistake I obsess over it. I try so hard to learn from it and not repeat the mistake. I admire those nurses who always look so calm and collected. But I can't get the worrying out of my head sometimes and that interferes with my work and my life. Does anyone else ever experience this? And how do you deal with it.
JMoney, remember dear, you are not God...lol You are a nurse. A very assertive nurse. We all make mistakes since we are human. Own the mistake, correct if possible, and move on. A nurse who says they have never made a mistake or med error is lying or is not really a nurse. At least you are aware of when you make a mistake and conciously try not to do it again. I have met nurses who just brush their mistakes under the rug, shrug it off, and they are definitely a hazzard to our profession.

If it makes you feel any better I'm the EXACT same way

I know I have moments like this. I try to not obsess too much. It's tough, but I remind myself that we all make mistakes.
