I just need some support really, I know there's not really any advice to be given.
Basically, my (half) sister's Dad is a massive alcoholic. It's been this way since she was a baby (she's 27 now), so it's not a new thing, and he's been dry for several years at a time during that time. However, the past 3-4 years, he has got progressively worse. He got throat cancer, and was put in a drying-out facility while he was being treated for it, and was told that if he didnt stop drinking, he'd be dead within the year, and he was dry for about a year.
The past few months, he's been drinking again. He was due to go and stay with my sister a few weeks ago, but couldnt make it onto the train because he was so drunk.
Yesterday, they went to scatter our Nan and Pops ashes. Her Dad was so drunk he couldnt even make it up the hill.
My sister called me last night and she was just sobbing. He is GOING to die, probably soon, and there's nothing we can do about it. I just want to help my sister, but I dont know how.
I hate her being like this, it breaks my heart for her to be so upset

Like I said, I know there's not really any advice to be given, but I just think I needed to get it off my chest.
