Well-made points by all. SBF's comments re: the so-called authentic self have me thinking.
Apart from my half century as a JW, I have always remained the stereotypical artist, temperamentally. Highs and lows, frequent crashes after protracted periods of productivity.
Now, at 70 years old, I remain, at heart and in spirit, that same soul but quieter, calmer, and less inclined toward impulsive (and often regrettable) behavior.
Not much to add, jp, but more later as I dwell further on your other listed items.
Well, I am through all five steps of grieving and loss. Acceptance of what my life has become is healing itself.
