Thank you for sharing your truths Tuned Out. The 3,000 Qs notebook (where I pull the Qs from) is really interesting. I surprise myself sometimes when I answer. other times I am reminded of issues I need to focus on. And some Qs are just fun or silly.
I wish you and your family member well as they work through a serious issue.
Perhaps you could try 'guided meditation for anxiety or letting go of thoughts' on Youtube to help you with focus before and after work? It helps me.
I often tell my partner that I wish my brain had an 'off switch.' He grins and says "Me too!"
