I thought this was an interesting point. It's one thing to have a horrible disease. It's worse to have a horrible disease with no effective treatment. It's even worse to have a horrible disease with no effective treatment and lots of people telling you that if only you did this, or that, or spent money on something else, you would be cured.It’s also, to me, quite toxic. It makes it so much harder to be sick with a horribly debilitating, untreatable illness when you constantly have people milling about telling you it is treatable and you can get your life back if you only do A, B, and C, and then maybe D, E, and F. Particularly because the people that do this systematically undervalue or dismiss the costs and harms of the treatments they propose, in ways you don’t necessarily see interacting with them casually.
The result of the last scenario is that it's harder to get on with accepting and adapting to your situation, and focussing on things like constructive advocacy that might actually change things. Perhaps everyone with a disease with no treatment has a constant nagging feeling that they should be doing more to get well, but for diseases like ME/CFS where even the doctors make unhelpful suggestions and think people aren't trying hard enough, I think that feeling is hugely amplified.
