Just a word on the reasons people say no to things, as it's been a proper eye opener with DH.
Lots of things which have been recommended by well intentioned professionals have failed, and that's ok - making it clear that nothing will be magic and give back your ability, if your lucky a tool working is just bargaining for a bit of time.
Tools like walking sticks and frames need to be learnt and practiced, and they hurt to use especially in the beginning, a caring arm is easier to use than a walking stick. The risk of failure can be enough to stop people trying in the first place. Persuaded DH to use one as I said he was pulling my back out leaning on me.
Refusing food and drink, oral thrush is really common and really bloody painful - and the medication is a fiddly medicine dropper four times a day. Taste changes quite a bit with it and everything tastes rubbish. DH refused it at first as didn't see it as a problem, until I said that eating is one of the few pleasures he had left and I showed pictures of his tongue.
Carers coming in for personal care - honestly, it's a complete ball ache, unpredictable times, and you need to be really specific about what's needed, otherwise it's a very brief wipe with a flannel which would make even the most soap dodging teen blush. I completely understand why people refuse them if they can possibly get away with it. I agree with DH that it's not great, but if I did a really good clean it would take three times as long on my own (and he'd be absolutely shattered) - so compromised on a twice weekly carer clean.
Falls have been much harder to discuss as DH believed he'd be able to get up with me lifting him, unfortunately, he ended up on the floor for over 5 hours waiting for an ambulance which never came - it needed to get to that point before he accepted his mobility had gone.
