Dear Gina! I've recently lost a sweetest of dogs, so I know what you are going through! Please be strong for your mom and yourself! I'm saying it, but I must confess I'm crying still at nights myself... You can't help the fact that death, pain and misery exist in this world and come into your heart... But think - what a happiness it was, that the years she was here, she spent with you! And I believe, too, that some day we shall all be together, and out of pain.
Hold on! My hugs, hugs and hugs, and a lot of sympathy.
