@bobbler You've raised some of my concerns which have been only increasing as my health has been deteriorating.
At one point on that downward trajectory, I have become painfully aware of the biases, beliefs and blame within the patient community.
This is an overly simple breakdown of some major observations that concern me based on my time in online communities and seeing what milder patients think and appreciate. Not all patients are like this. I think some problems you talk about stem from what I've written in the rest of this post but you've definitely touched upon wider problems than me here.
First, there's a common trap of attributting improvements to whatever they're doing (lifestyle, off-label prescriptions, supplements, mindset), overconfidence about their understanding of science, subscribing to simplistic pseudoscientific explanations and little ability to identify even the very obviously rubbish papers as crap.
Another one is just celebrating whatever becomes available to us in terms of services and healthcare options, seeing everything as a positive step forward. Furthermore, one might be called out for being negative and difficult at any hint of criticism.
Some patients who still have some quality of life speak highly of the OT who thought them how to colour code their activity diary, physio who's helping them strengthen their body, nurse who made them feel heard and validated when she told them their symptoms were real and not in their head but proceeded with treating them as if it was all in their head. Those patients highly value and call for multidisciplinary holistic care. In addition, some patients who weren't happy with the multidisciplinary holistic care they received are calling for better multidisciplinary holistic care based on the current model.
Finally, some patients show obvious disbelief that things can get really bad through no fault of the patient. The patient must be doing something wrong if they're getting worse or if they've deteriorated to severe/very severe. Some patients refuse to see the lack of care once you cannot leave your home. Common advice from a privileged position is to have private online appointments which also fails to recognise the limits of tele-healthcare.
I'd like to think that someone with any of the aforementioned views wouldn't engage in advocacy but I see it happening.
