Sorry @angelinlothian, but I have only read your OP.
My MiL was - by her own choice - living in a (hospital) bed in her lounge, rather than in a nursing home. She had carers coming in 4 times a day, for both domestic and health care reasons, plus her amazing niece, my DH's cousin, checking up on her almost daily.
Unfortunately we, husband and I, lived 5 to 6 hours away by car, and had our own heath problems, so we couldn't visit all that often, but would stay for about a week in a hotel each time we came to see her. The carers were in daily contact with her niece as she lived locally, and is one of the few people in life who truly cares for others. We owe her so much, but will sadly, and probably, never be able to repay her, in any meaningful way, which we feel very guilty about.
Anyway, the carers told her that MiL was deteriorating quite rapidly, so we rang her Dr - this was earlier in 2019, several months before we became aware of Covid 19 - and I asked the doctor to visit my MiL urgently, that day. This was at about 11.00am, but the doctor, who knew all about my MiL's illnesses, and that she was so disabled and ill that she was bedbound, said he couldn't fit in a visit to her that day, even though she was in terrible pain. So I asked him to go in his lunch hour as it was so urgent, but he replied "what about my lunch?", which is when I lost it, although I managed not to swear or shout, but I did tell him that my MiL was a very old - which he already knew - and very ill lady, who was in a lot of pain, so he could either go without his lunch for once, or eat a sandwich in his car on the way to see her! He went. As well as upping her morphine, he realised that we, her family, had also been right that she needed to go onto end of life care, which meant she also had a night nurse at last.
I was the one who talked to the doctors etc, as I had some kind of medical background, and I could be - normally - quietly insistant. Also, my husband asked me to do it, I wouldn't have just taken over from him! Again, as a family, we were very glad for MiL's sake, that she died before Covid 19 was much more than just a rumour.
I am in my late 60s now OP, and can remember that as recently as 2018 I still had the same family doctor that I had seen in our multi doctor practice for the last 30+ years. He knew, and had been the doctor for, all my children as well. How has so much changed in under 10 years, and so much for the worse? I'm very sorry that you are now also a victim of this awful crumbling national health service, that was once envied by so much of the world. So I don't think you are being at all unreasonable @angelinlothian.
Hopefully, without sounding condescending, I can say here that younger women might not realise that once upon a time, and not actually that long ago in reality, GPs had ethics and morals, and they would have never put such an early home time before their patients who needed them! They were, and presumably still are, given a salary that reflected their now, apparently gone, work ethic, and their genuine care for their patients. I do hope that you get the help you need very soon now, OP. 💐
