Welcome to the forum - sorry I'm a bit late Image
I care for my partner and it also took me a while to realise the amount of care I give over and above just being a partner. My OH also stumbles and falls a lot and after an OT assessment we have been given an inflatable cushion/chair thing powered by a compressor in case of an emergency to enable him to get up from the floor. Just thought I'd mention this as it might be a useful aid for you too.
