i know exactly how you and your daughter are feeling... i was living on my own as my parents had moved and i was just waiting for the school year to be over before i moved and i had our cat for 12 years and i had to make the decision to put her down.. i was lucky to have an uncle to bring her in for me... but i remmeber having to say good bye to her and it broke my heart like nothing else... i feel for the both of you.. time will heal and until then tears help
praying for your heart to heal.
