So if she's been in bed for weeks her son most definitely isn't staying with her then?
In which case she needs to get rid of her admin, who appears pretty pointless anyway. £££ saved there.
I can't see where else she has actual regular commitments aside from the photo selling etc. So cancel that for now and time saved there.
Sell the Emin, water rower, maybe a few sideboards, some other crap, £££ made there.
Live off the rest of the money put aside, as she was only giving herself a living wage. £££ found there.
Give notice for the bungalow rental. Lots of £££ saved there.
Find a nice 1 or 2 bed affordable living space, pick up whatever jobs you can find, and live within your means........like the rest of us mere mortals do.
She's so lucky that she has the flexibility with work that most of us don't, as well as being able to put aside some of her earnings. Imagine feeling like that and still having to go to work in low paid job because there is no other choice.
