I find the better rested I am, the more able I am to deal with stress, or even needy others. Nursing is hard even under the best of circumstances, so for you to be rest deprived, puts you in a struggle catagory. Your main goal is to take good care of YOU first. then take care of others. Just like on airplanes IF the O2 masks falls, put YOUR mask on first, then put on your childrens.
That was a hard lesson to learn for me as a caregiver. Nurses are so stubborn.
