My husband was hill walking with our dog in July, now he lies dying in a hospice bed 6 months later. I feel overwhelmed with sadness at what's happened to us.

He's at the stage now where it's difficult for him to speak,  because of pain medication fog. He can't write, read or watch TV. He can't move his body. He is also overwhelmed and depressed at what's happened to him. 

I visit him every afternoon, but we often just look at each other and cry. I want an end to his suffering - but it goes on and on. 
I dread going in to see him now, because little by little I am watching him die.
