@Glennponderwelcome to our midst.
On the cleaner front it’s worth persevering to get one your DM likes. I ignored DMs complaints about the first one I managed to get in, but then various events conspired and they got a new one that they both now seem to like and they agreed to increase her hours to help DF put away the groceries and keep an eye on items in the fridge so that’s a minor weight off my mind.
The constant feeling of stress is the most draining part of this for me. I live an hour away from DPs, am currently not working but starting a new part time job next year which I am looking forward to as something else to focus on. I have only been doing heavy duty responsibilities for around 7 months - prior to that point DPs were gradually deteriorating but just about functional, but then DM had a fall her speech is more or less gone, DFs dementia had suddenly ramped up and it’s all been a bit of a train wreck since.
As we are in Scotland DPs get various free carers which just about do the basics and means they don’t want to use their vast wealth on getting more coherent paid care in and DH and I pick up the rest ( only child). Because they have carers in we have managed a few holidays but there is always the constant worry about will something happen to prevent us going, the dread of the phone call when we’re away and the aftermath visit that inevitably results. I have gone on HRT a month ago purely because of the stress and have put my phone on silent so I can phone when suits me, rather than sometimes responding badly.
It sucks big style and is not how I want to be spending my 50s.
