Good Morning. As long as you can say you did your best and gave 110%, then you had a good day.
I agree with Medik8, and if we could save them all, we would be out of a job.
I remember my ER clinicals, with a code. The doctor had to crack the chest, and I was manually pumping the heart. Unfortunately, it was only successful for a short time.
Continue all your hard work and dedication to EMS, because it can be very rewarding.
Feel free to vent, I will always be willing to listen as well.
Take care.
