That verse today can be interpreted literally and figuratively.
Fwiw, my mental health had to look up to see the floor, for decades. There were moments of happiness, even ecstasy, but the baseline was low. You've probably read enough of my personal mental health experiences that worked for me, so I won't rehash them here; unfortunately, what works for one doesn't work across the board. I wish for the most favorable outcome for both your mental and physical health. And I will be glad when your landlady returns.
Thank you for your well-wishes. It's in the works!
