I wish I could say or do something to make you feel better, to stop the hurt.
But I can't and all I can suggest is for you to stay close to Him and let Him comfort you.
I believe you will see them again where there won't be any more sickness, death or pain. That's why we sometimes call this time "bitter-sweet." Bitter because we grieve for our loss, sweet because we know they are in that wonderful place, no longer burdened by the limits and failures of this earthly body and waiting for us.
I'll keep praying for you.
Bob
