I have posted before on this forum. I am at the end of my tether with my parents denial in old age and things are gettiing slowly worse. I don't know where to turn anymore and it is affecting my own mental health dealing with it 
They are in their early 80s and living in the house they've been in for the last 40 years which is a semi detached and no downstairs loo and nowhere near any amenities. There is also a neighbour dispute spanning the past 30 years so I can't for the life of me work out why they stay there. To cut a long story short, it isn't accessible for my dad who has terrible mobility and toilet issues. They keep shopping in the car boot as they can't carry shopping bags up the path! 
My dad still drives and to be fair, his physical driving does seem ok, however it is obvious his driving days are coming to an end soon given his age and other abilities. When he stops driving he will be housebound. This is another story for another time but their answer to that is for me to step in and drive them around even though I don't drive and have 3 young kids, 2 with ASD. I will certainly help them out when I can but they have isolated themselves.
My mum is a narcissist and doesn't like being told no, I get guilt tripped and digged at constantly about this. She threw a total wobbler when I told her I am not driving. My parents won't pay for taxis and for appointments they don't want nhs transport because 'the neighbours will see it' 
. Very much Hyacinth Bouquet style, what must people think. Any time the car is in garage for MOT or breaks down she goes crazy and can hardly cope. It is embarrassing. I dread the day he stops driving. My dad is so passive and is controlled by my mum, he is like a little boy and does everything she says.
My mum whines 24/7 about 'how hard life is', she can't handle getting workmen, gardeners (when they aren't mowing the lawn themselves with one at each end of mower handle ), moans constantly about the noise from the neighbours. I often come off the phone to her wanting to burst into tears. I actually can't carry on like this for much longer.
They are in the habit of blaming outside factors for everything. It is the council's fault that the bus stops are too far apart, if they get lost they claim road signs have been moved (when they've not), lockdown is to blame for my dad's senior moments, etc. These are only a few examples, it is unbeleivable the things they come out with. Anything except face up to things.
Recently my dad has also been having many what my mum would describe as 'senior moments'. However I have suspicions there is more to it, however my mum will never admit it so that's another struggle I potentially have on my hands .
I am so stressed and frustrated with them, and just want to tell them to take repsonsibility for themselves and stop moaning. I actually think they sometimes enjoy the drama.
