Seems you've nailed something...as what you said resonates with me especially the last couple years entering my 40's. Still have those times, and situations of "darkness" for lack of a better term, but learning and definitely feeling different in a good way overall.
More alone time (from humans - not plant, animal and insect friends in nature) has played a part, and
led me to ironically meet some really cool humans that share the same feelings!
I think your ramblings are motivational words of wisdom
