NC for this.
Background - I've been semi-estranged from my parents for nine years. Very very LC (no IRL visits and only a very occasional email). Religious homophobia (I'm bi) was the catalyst but not the only reason. I don't know if I'd call them abusive, but they were definitely suffocating, controlling and blamed me for not being the exact ideal child they wanted.
My dad died last year and I went to the funeral despite only feeling relief that he was dead. It was the first time I'd seen my mum and sister in a decade and they essentially pretended the estrangement had... never happened? It was surreal, uncomfortable and triggering (my therapist has long recommended full NC).
My mum's health is now declining. In keeping with her denial that our relationship is anything other than completely normal she apparently wants me to have power of attorney (my sister isn't really up to the task mentally). A family friend has emailed telling me to take time off work to travel back to where my mum lives and sort out their financial affairs.
I can't take time off work, I have a very demanding job. Well... I think my company would actually give me compassionate leave, but my absence right now would leave them very short-staffed at a crucial time of year and frankly I don't want to take time off work for this. I'm also trying to buy a house at the moment and any leave I can grab will go towards that process. I don't drive (I live in a city), and getting to the rural area they live requires the best part of half a day and three separate changes of public transport.
I don't know the first thing about power of attorney, or what state her finances are in. How demanding is it in terms of time, emotion and possibly my own money? What happens if I say no, and there is no one else who could take it on? (My mum's family are paying for her care, they live abroad. That there is no better candidate in this country to have power of attorney than her semi-estranged daughter who she's seen once in a decade says a lot.) I don't know and don't care about any inheritance.
And despite the semi-estrangement there's still a lot of guilt I'd feel about essentially abandoning her.
