Hi, I've been a nurse for 7 years now, and I promise you that the first year is the hardest. I was a flight nurse in Iraq... and that was nothing compared to my first year as a med/surg nurse. Be kind to yourself... it will get better. Try to "put the monster in the box", that is, let things go. Don't think about work when you aren't there. Everyone makes mistakes- nurses, doctors, everyone. Just do your best, know that everyone felt or feels the way you do, and be gentle with yourself. I promise you, it will get better.
