I just want to clarify this: my dad is completely innocent here. He's been a saint about all this. It's not his dad, it's mum's dad, and yet he's been there for pretty much all of grandad's incidents, he's been the one coaching him through how to do basic things, he's been the one fielding grandad randomly freaking out about stuff that's only happening in the fading remnants of his mind. I've done what i can to ease the burden, but the majority of it has somehow ended up on my dad's shoulders.
He's given so much time and energy into looking after grandad, despite being under no obligation to at all. And he's been having to do all that because grandad's actual son, my uncle, is the one with power of attorney he
refuses to use to make the necessary hard decisions. Dad's also gotten on board with my argument that grandad needs to be in a care facility, but he's also powerless to change it too. It's part of why i'm so angry about it, i'm mad for both of their sakes. I know it's irrelevant to the overall point of the conversation here, but i just want that on the record wherever the record exists.
As for the relevant stuff, thanks Witty, i appreciate the understanding and kinship. It does help a bit.

I feel a bit daft, complaining i'm white-knuckling sobriety before i even became a full addict, but god it sucks how badly i want to solve this problem with alcohol, knowing what it would imply if i did.
