Hi Terry,
I'm about a month older than you. I, too, have PTSD but from being an infantry rifleman in a war. You didn't miss anything. The good thing is that we've both outlived about half the folks who were born when we were.
I think I get what you were saying about your artwork. I went to an art class half a dozen times about four years ago and started an oil painting. I took my painting home and did most of my painting there, which at first frustrated my instructor, but eventually she said, "You got it." I really don't know how I did it and became frightened that if I touched it again, I would ruin it, so I never did.
I went through a divorce about 10 years ago and left the cult shortly after that. A couple of years later, I got married to a wonderful, positive thinking lady and have not revisited my deep depressions since.
Your story is fascinating. Being a Jehovah's Witness AND being successful is almost an impossibility. Glad you got out.
