Now What?

I'm kind of floundering - how the hell do you deal with something like this? Is there any way to deal with knowing that you father is going to die, probably sooner rather than later? Any way to stop feeling guilty for not pushing him harder to quit smoking? Or for not making him go to the ER sooner? I just... I just don't know, and I don't think reading (books are normally what I turn to first) is going to help. I'm thinking of going back in to Community Mental Health for counseling, because I"m pretty sure that talking to someone who's not in the middle if all of this will help.
