I am sorry for your loss, but am so glad that you have found a way to "work" through the sorrow.
It is my experience that bad events tend to cause some to throw up their hands, stop living, and begin causing pain for others.
You have found such a wonderful way to make the world a better place in spite of suffering incomprehensible loss.
God bless you and keep you and I thank you for the example you have shown to others.
Sometimes, the best that can be said of painful experience is:
You have shown us a better way. <wave>
