Hi Adrienne, I think that we all experience this at times we are all so busy just living these days, I call it brain lock where you get to that point where nothing is happening, like stalling a car.
I find that having a plan and working it really helps and over time I have learned to be realistic with my expectations, tomorrow is another day. Definitely functioning quite reflective times through the day works as well and when all else fails, nothing like doing some real physical activity.
