Keith, my friend, here is my 2 cents...
All of our experiences in life add up. The good and the bad, the helpful and the unhelpful, the pleasant and the unpleasant, the positive and the negative, as well as all our 'highs and lows'. Once we have seen, heard, felt or experienced something it becomes part of who we are. There is no 'reset' button to our lives or a subtraction button like on a calculator that we can use to remove things from our consciousness and human experience. The sum total of every minute that we draw breath makes up 'who we are'. You seem to be a very 'sensitive' man that is caring and considerate. A very fine trait to have although it can cause unnecessary suffering at times. No doubt, your children may have inherited the tendency to be 'sensitive' ( I mean this in the most positive and meaningful way) and therein could lie the problem. When you share with them your thoughts and feelings about your life experiences, especially with the Jehovah's Witness religion, it may produce unwanted reactions inside of them and they may want to 'push away' the unpleasant feelings by stopping the conversation midstream and announcing that 'you should just get over it'. Of course, they have their own set of negative life experiences that they have to deal with and probably are overwhelmed emotionally sometimes just trying to get through life still struggling with the excess baggage of being raised as a Jehovah's Witness. Maybe it would be best for all concerned to sit down and have a heart to heart discussion about your 'common' issues. Honor your emotional pain, and allow them to honor your pain . Honor their emotional pain, and teach them to honor their pain. When the 'common issues' are brought out into the light of day, talked over, examined and acknowledged then they will begin to lose power over your life and the lives of your children. I wish you all the best, Keith. Some of my life experiences are similar to yours and I have fellow feeling and compassion for you.
