I am praying for you and your mama. It is so hard when others get sick and we are not feeling well ourselves. Someone posted this in her signature: 'I wish God would let me fast forward through the bad times' - I couldn't have said better myself.( I wish I could remember what board and who said that but I can't!)
I suppose that we cope with them the very best we can. And the rest - the rest is up to God.
