I understand how you feel. I have six of my babies home with me, but as soon as I got the call from the vet, I was in the car and off to bring them 'home'.
Today I can laugh about my Little Ray of Sunshine, our Siberian Husky who always travelled with us in our motorhome. We towed the Harley and whenever she saw us getting it ready for a ride, she would jump all around it trying to get on. DH told her she couldn't reach the pedals so she couldn't ride it!! When we had her put to rest and got the call that her ashes were back, DH took the bike to bring her home. Said she always wanted to ride it and this was her chance.
Take someone with you, you will probably be crying all the way home.
