I left in 1979, probably before most of you were born.
I left for mental health reasons. I could not tolerate my existence and lack of hope. 1975 had come and gone. I was still young enough to get an education and build a life. I realized that I was not a better person for being a JW, but, in fact, was less kind and loving than I had been before I was a JW.
I left my elder husband a note and left. It was tough, really tough, in those pre-internet days. But it's the best move I ever made. I do have a life. I have a college degree. I'm even beginning to have money. I can look forward to a good retirement.
If you are afraid to leave, I recommend that you read Your Erroneous Zones by Dr. Wayne Dyer to get yourself started thinking in a more healthy way. It worked for me.
Best regards,
SandraC
