There is nothing wrong with taking a break
When my 4 year old is having a hard time listening, we practice deep breathing and taking a break. We sit on the floor and take deep cleansing breaths. He is able to flush out some of his emotions and move to a calmer state where he can hear and listen. This helps to calm and recenter him, but it helps me, as a mother, to be patient and to see the bigger picture.
When I was a child, I took for granted the ability and the space we had to nap. As an adult, I do not take advantage of rest, as often as I should, and I recognize it. Today, I did little in terms of being "productive". I woke early, did some work, got a mani/pedi, and then decided that I didn't have it in me to DO anything else, so I took a nap.
I didn't really sleep much, but I rested without cluttering my mind. I relaxed, not over thinking about the things that I could be doing. Instead, I closed my eyes, dozed a bit, and let the TV watch me as I floated in and out. When I was done resting, I felt so much calmer and lighter.
Resting gave me power. When I "woke" I was able to see that the to-do's floating around my head, were so easily put to rest. They were no longer these hard thoughts to conquer, but simple tasks that would easily fit into my day, another day. I feel like I hit a reset on my brain.
Today I took a break. I hope you gave yourself one too. When you find yourself sleep- deprived, overwhelmed, or lacking the energy for the day, do what your body is telling you to. Take a break and emerge energized and more thoughtful. Let me know if you're able to hit reset this week with a bit of a rest.
