Dear serotonin2
I believe as you mentioned in your post that you know what you are doing though the stressors of the responsibility of caring for another human being's life takes a toll at some point. This job is physically and emotionally exhausting so take time for yourself, go for a walk, get your nails done, anything that you like and enjoy doing that will take your mind off the job and its duties. At some point or another , we ALL whether is a new nurse or experienced one has felt overwhelmed at least once. You will look back some years from now and realized it was just a small set back and you will be able to understand if someone else is experiencing the same situation and provide empathy and expertise. Keep it up, you have what takes to be a good nurse. Anyone can can pass meds, check vital signs and perform a task , though not everyone is able to CARE for her patient.
