Dad just died...

My father has been sick and had chronic pain for as long as I can remember. Wednesday night I called 911 because he was having chest pain. He was diagnosed with pneumonia. He was in so much pain, I knew he wouldn't last long. I think one of my dogs knew he was dying because he sat by him until he passed last night... He'll never walk me down the aisle. He'll never meet his grandchildren. I'm just lost right now :(
