My understanding is that what you describe is included in the category of very severe ME/CFS.
I am very sorry that you are suffering so severely.
I get the point that for some reason at whatever level we seem , just as most others writing descriptions do too, to be ducking the core feature of how the illness works / needs to be described
which is that overexertion does lead to deterioration, not just PEM or fatiguability meaning our arm shakes at that point (but that threshold at which our arm shakes reduces)
true in some their threshold + situation means that this can be imperceptibly slow ie I was pretty sure I was getting 10-15% more disabled a year when having to work full time and certain things not being adjusted snd EVERYONE around me just ignoring that trajectory as if it would change for the better (for no reason) if my struggle and warnings were just ignored rather than accelerate , which is the LOGIC of the illness tgat needs to be understood.
and that 10-15% git hidden by me having to work out new ways of being tenacious with the impossible and of course if people don’t see you there are less occasions you have to fake it with a smile on your face.
Most onlookers defy that logic as having to do twice as much as your threshold isn’t just a horrific life but reduces that threshold so that then ‘twice as much’ is less exertion than it was before . They defy logic because they watch year on year someone saying unless they believe that action—> consequences and others start behaving more kindly to the pwme they’ll get worse, then they watch that person get worse - say 8 years/times in a row. And then still choose to change nothing and the next time the same person explains please can people hear them and bring what they have to do daily to survive or noise thrown at them under their threshold, else they will get worse , they again don’t - or manana manana it until that persons threshold is reduced again and they then need even more adjustments
this disbelief that many end up as severe as they are due to the thousands of papercuts adding up as reductions in thresholds (as consequences) each time , which are then even less believed is what. Is destroying lives and meaning people die
it’s also why mild isn’t taken seriously and why unless someone can be in the very rare position to control everything in their life and environment we get people not having their jobs reduced to part time or different hours due to disability- because people aren’t made to understand that will lead to longevity if done fast enough when some takes a downturn ‘getting ahead of the threshold’
if I could underline where the ME community has massively failed it is on this point being put across - the point of what the illness actually is, the ‘in good time/stitch in time’ otherwise any adjustment done six months too late is done after someone deteriorated and now needs a new level of adjustment
but vitally we are watching those more severe getting invalidated but also harmed because we are not - and I put this very clearly in the fact sheet project discussion- noting this. So we have in hospital people saying ‘it can’t be ME because it doesn’t get this severe’ to poor souls who got put thru GET, put thru desensitisation, put thru anything other than tears of proper care bringing their environment under threshold and then blaming the patient for ‘being worse’ rather than taking responsibility that those continued assaults on their threshold- which those things are defined by/as ARE what have done that
