Light you have been on my mind as I could feel your utter despair just as you were falling ill.
Although my mum never made it into hospital I did have to set everything up myself when she deteriorated really suddenly.
Phone social services and ask for occupational therapist to call you back urgently. They sent me items for Mum prior to them even visiting, so within a couple of days I had a raised toilet seat and rail, a bed rail and a zimmer. Once they visited they ordered further stuff like a hand rail for her stairs and a perching stool for her when she's in the kitchen (though maddeningly she's put it by the telephone table in the hall and tells me it's not a particularly comfortable seat for long conversations
)
The Red Cross can also loan you emergency equipment like wheelchairs, commodes etc. The OT did offer my mum a commode but she prefers to struggle instead
. I googled and found the local branches near me, phoned and was advised what equipment they could supply and when / where I could collect it from.
Your local authority will have a ceiling of savings and if your parents have savings below that level then SS will pay for carers. Above your parents will have to fund it.
Organising all this is incredibly hard work and you'll probably get no thanks for it either but it is worth putting your foot down.
Tell SS adult services team when you phone you cannot cope with constant demands / live too far away and they need to come and do an urgent assessment. I believe it was my breakdown on the phone that got things moving for my mum.
Check out if there are charities or other council initiatives to help you / them. Also go see / ring their GP and ask for them to signpost you / your parents for the appropriate post hospital and long term support.
I truly hope you are able to get it all sorted ASAP but I also believe that you have been conditioned to dance to your dads tune and it's a very hard habit to break (on both sides). But once you start putting yourself first and saying no it becomes easier and easier to say each time you have to say it
