Dear Kat, my heart goes out to all of you. We lost children in our family too and it is the most devastating thing ever. If you have "Compassionate Friends" (Bereaved Parents) Group near you they do a wonderful little book "Helping each other through a time of grief" that is almost unbearable to read but has some wonderful poetry and thoughts from people/grandparents/friends in a similar situation.

You could also try some homeopathic Ignatia .. any thing helps but mostly it is just time.

God bless, Hille
