Dear Jorola,
Oh, how I can feel your fatique and exhaustion. Working a high-powered job and care-giving together are really a huge load. Chances are sleep isn't enough or deep enough, either. One little thing that I have found, to give a bit of a boost through the day, is tapping on acupressure points on my face (as long as folks aren't watching). Or sometimes I just tell myself, I'm exhausted but I'm a good person and I'm doing the best I can.
I send you deep breaths and much care.
Nouce
