I thought I posted on this thread! Guess it didnt go through. Anyway... said I would find this letter technique. I really like it and hope it works for you to either work your feelings out on your own or to give to them.
I hope everything works out for you and all your children

.
I’ve used it to give to people and I’ve used it and not shared the letter also. So its to share or for journaling.
