I am not sure if anyone can offer any advice but perhaps people have experience of similar situations.
I live 80 miles away from 90 year old mother who has multiple health conditions and was given months to live two years ago and a maximum of a year to live in early 2023. The good news is she is still here, the bad is that she is living an isolated and miserable existence but continues as she is because she will "soon pick up" , according to her.
She has had multiple professionals involved , who strongly advise respite or care at home, all of which is refused. I am the only carer and am needed every week for shopping, cleaning, washing etc whatever else is happening with my family or work. I would visit anyway but I hate that she has no local carers whatsoever , in case I am unable to get to her and no one else but me for company and support. Having frank discussions ends up in her getting angry and upset. Allegedly she has capacity to make "unwise decisions" and boy does she and regularly!
I have a strong feeling of resentment mixed with guilt at how I am feeling mixed with dreadful anticipatory grief at the inevitable loss that I am facing.
I realise there are no magic solutions and sending good wishes to all coping with way more tricky caring situations than mine 💐.
