Oh dear, I'm so sorry for your loss. My heart aches for the pain you are in right now. It hasn't even been a year yet since I loss my sweet little Annie B, I was blessed with her for 7 years.
There are no words that can be said that will help right now, just hold onto the good memories, they will help you through. Borrow strength from us here, we grieve with you and will help carry you until you can walk again.
