I don't know what to do...

I'm at such a loss. I don't know how to help P with the seriousness of his Dad's health. He's exhausted today from not sleeping last night. Today he called to say that the hosptial was letting his Dad go. I think P has all these thoughts running through his head and doesn't know how to process them and isn't sure he really wants to process them. Who really wants to think about the progression of a parent's death? And to make matters worse, this will be the second time thta P will have to go through this in less than 15 years and he's only 40. It makes me incredibly sad for him and worried about him.
