Yes, push-crash is often expressed as a cycle. We need something that conveys having so little functional capacity you're never able to escape that cycle.
Nailed one important issue there. Robbing Peter to pay Paul/APR technically does it but not quite conveying the severity of the situation yet. I think that is where most of us end up forced to live because even kind human beings have implicit in them not to give what you fully are asking for (or there needs to be additional compassion/want to understand the extent when they do it) - someone getting something for you but calling you 4 times to get you to repeat what you already explained defeats the energy-save (and being able to do the bits when you weren't feeling as bad).
They really can't imagine from what they see that you are stuck in a situation on 250% of what you should be doing just to not even tick the essentials across a fortnight (that you've filtered down, so shower and toothbrush exchanged for medical things etc and the 'twice a day' idea has to be already seen as 'nice to have' and you also are talking about 'minimum before I'm creating more issues for myself').
Then you look at the understanding of those who are very severe when they end up somewhere that isn't home with very understanding carers and the controlled as much as possible environment there. I'd imagine it becomes so many moments in a day you can't say something every time and people don't believe the implications, but when they see them later in a deterioration or sleep being interrupted attribute it to something else.
There isn't yet a chart (seen one recently that conveys the idea, but doesn't get the proportions right) or video (I note these are very good for things like ADHD etc for being done not in an 'you are going to be educated' way, but inviting people in who might be curious about what life is like in reality - but it's risky giving how sorry I can seem at my worst and potential bullying),
and I think the most useful medium will be video game/game type things. Where of course increased severity increases the 'level' - a sort of virtual reality-ish combo of the sims, combined with the sort of markstrat thing (not very hi-tech used for marketing strategy 'games').
But also this sort of thing can bring alive how the deterioration and invidious choices and spiral gets put on people without incredible support, fortunate circumstances and somehow being incredibly protected from what has been created as policy from too many 'services' etc. Things like 'erk you do that change to your hours and your salary won't halve but you are only offered a lower job, so salary decreases a lot more
and you have less control so it might be worse' when someone tries to solve the puzzle of 'how to make life add up'.
And can realise that without that building work/noise from neighbour (that they think is no harm) stopping it won't add up/you won’t recover from any PEM despite being given it so can’t avoid going downhill. As you get worse you get rewarded with more work from medical appointment or prescription or filling out forms/appointments for something else that turns out not to be on offer for us.
And that people have to start with grim things like not saying hello to people in the street they normally would, refusing to even go to the whatever bit of whatever wedding, not helping lift those boxes when your colleague is landed with a massive stack and you normally would (and look capable now, but it is already 50/50 if you can eat dinner that night or you'll be crawling straight to bed and unable to lift your arms already).
How that's exactly how someone ends 'stuck in bed all day' relatively quickly when it is your own life.
And eventually either because of their own needs (wanting to extract themselves) or I think it has been so drilled in, certainly in any professions, those who have been management/manager rather than underling and probably in 'busy types' (mums who are working etc) in fact the list is endless ... they switch to 'coaching' by starting to leave bits undone, yet having started or promised something etc.
...just because time passed, so you must be ready.
