"Me time" is sweet. We need it. I'm glad you are finding a way to have it in your life.
You've shared much with us on this site. I know some of the ongoing stress and challenges you face. So yes, you need me time. You also need sleep nourishment so you can be at optimum functioning as you deal with your complex life.
I just learned that the brain acquires metabolic toxins just from being awake. During sleep the brain cells shrink creating more space for those pesky toxins to get swept away.
I hope you are giving your body time to sweep out those "mt's" from your brain so you are as fit as you can be for your days.
