Oh Bettyanne. I am very sorry and can relate to so many pieces of your life as the child of an Nmother. What is exhilarating is that in spite of the pain of realization, you DO realize all this now, and your narrative is so clear.
So you're in your 70s now. But it's not a time to give up, decide your life was ruined by an N, and so there's no real point in the present.
THERE IS a point in the present. Now is when you get to learn to release it all, let go of everything you didn't cause, couldn't control or cure in your past.
Whatever you find that helps you do that...will lead you back into the present. With its breezes, and sunrises, and music you've never listened to before, new books, new faces, different experiences whether simple or big. Something creative, something comforting.
Don't ever devalue your life, your being, your enjoyment, and your sense of dignity and peace. You deserve to savor what's good, simple, beautiful, peaceful and bigger than all that history.
Now you can plug into happiness. One little piece at a time. And keep savoring it every day in every possible way, small or big, until this chapter of your life becomes the richest and most rewarding of all.
hugs
Hops
