Not quite.
I have felt my issues were different in that my mother is physically well but having no memory is a real handicap. Experience is that I am having to do quite a lot myself, eg take her for a flu jab etc. Plus my dad was a bit of a buy-to-let enthusiast and until I get a family consensus to sell, I need to manage these. So six hours in the car to give keys to a plumber as the agent could not find their set.
Then should my mother have a health crisis or a fall, I am back to three trips a week or more, and this time not able to stay in her old flat.
Physically my mother is at least a couple of decades below her actual age. Once the first crisis was over I got quite depressed about the long term commitment. If she were to live to 100, which is absolutely possible, I would spend quite a lot of my active retirement on the motorway. Assisting our parents in retaining as much independence as possible, means less independence for us. In part perhaps it was the awareness that I could spend more years looking after my mother than I had spent raising my children.
We have just paid off our mortgage and so, though I am not particularly happy about the financial implications, a small flat accessible to the railways station seems the best option. I can then go down during the week and DH can take a train down at the weekend. Kids are at the UCAS and GCSE stage so we will soon have more freedom. (Am I allowed to veto applications to local Universities?) My mother wont move to London and in practical terms it would make no sense. Luckily she lives in a nice part of Britain near the coast.
I feel relieved that I have finally found a solution to an issue that had been gnawing away. I know others have long drives. I have been finding that the drive plus the stress of dealing with hospitals or whatever, meant that I remained pretty wiped out for a couple of days after.
All a bit of a first world problem compared with those faced by others. I plan to offer the flat to extended family provided they call in on my mum. This should increase the flow of visitors and as her world contracts, mean she is less reliant on just me. Not sure if it will work on the invisible brother.
Good luck with the GP and solicitor. It sounds as if action is needed. Any progress on your brother. And I hope you get some sleep. Hang on inn there and hopefully I will be able to offer you a week by the seaside.
