Im the position of having 2 carers x 4 times a day for the past 5+ years. I live alone and am often bedbound, 95% housebound.
You cant cope - keep repeating that. Tell everyone you can that and ask them to put on the notes. This is dangerous to your mum to let her home like this.
My package is based on my physical, neurological and mental health needs. (MH has only tagged on as apart from seeing a cpn monthly / psych 6 months - that the lot).
The longest calls are 20 mins and other calls are 15, there are times we cant fit in changing bed and me (incontinence) and food in the same call. Its microwave meals only, sandwiches or toast.
I've been discharged in the past when I could barely speak and had little use of my whole body, could barely hold my head up. It was hell as I went home on the transport ambulance they arranged and was put in bed, the on-call consultant deemed I didn't need any care.
As was leaving the ward, the nurses had made bets about how long it would be till I was back and what damage would have occured, I couldn't even feed myself much less anything else.
The GP called the next day and had a complete meltdown as I was lying in my own incontinence, dehydrated, starving and even more ill in the first place. I couldn't hold a drink to get it even it was beside me.
She got me back to hospital asap after speaking to the main consultant I was under, neurology didn't have any actual beds in the hospital so I was in a medical bed and the medical consultant considered my condition to be mental whereas neurology considered it to be neurological and had recommended a full care package be set up which didn't happen at first, friends left me a load of pj stuff and I told them to walk away and take my house keys with them.
So no one to pick up the pieces, a supportive dr who liaised with social services with input from GP, and lots of assessments followed psych, OT, SALT, physio, other medical disciplines, tests and finally a multidisciplinary meeting and the care package that would help alleviate things for me. The hospital SW was also a valuable resource too. There will be one attached to the ward even A&E although they should get a consult from pallative care and their input.
This has been re-assessed many times over the years. Things are slightly better than the original admission but a good part of each month I am right back there.
The girls help me meet basic personal care, administer medication, food (cereal /toast/sandwiches / ready meal) and generally keep an eye on me from falls, mental health etc
So op, ask for all assessments OT, physio, psych, psychology, a home assessment, district nursing.
Don't leave till its all in place. Last year I had an emergency admission via a&E as new potentially dangerous symptoms, anyhow they turned out not to be what was initially feared (cauda equina was the fear), but it took a while to work out what was actually going on.
Anyway after a couple of weeks in hospital when they considered could do no more and physio had done all they could, time was going to help the rest, they sent me home to the care package with community physio input.
Unfortunately for me, they referred to the wrong physio team so after 7 weeks I found this out so the GP then had to do a referral which then went to the correct team, however, there was a 4-month waiting list to see them urgently.
So you cant offer help, you are working 10 hours a day, no shopping there will be a way around it otherwise the daughter will be seen to sort shopping and when dropping it off you can do x, y and z and your time will be more and more drawn in.
I've also spent time in a nursing home while providers were being changed as one company couldn't cope with the constant flucations in my condition. Im early 40s now so not elderly but have a full understanding of how this is hard for all concerned and asking family and friends to step away was hard for us all, I knew I needed help and if there was someone to pick up the pieces, it would be thrust upon them.
