'for some sufferers, having M.E becomes entrenched in their psyche, part of their identity'.
No.
Some people(and I'm not even referring to myself here, I'm referring to the many sufferers worse off than I am) just have such a severe experience and long drawn-out deterioration, or even just continuation of the state of the suffering, that there really is no option but to be rather brutally honest and upfront about the realities for many sufferers. When there are many sufferers bedbound, emaciated, being fed through a tube, and their bodies are slowly shutting down, you cannot dismiss that as 'entrenched in their psyche', and it's incredibly offensive and ignorant to do so.
Positive thinking doesn't cure M.E. In fact, there are no known cures for M.E. One of the major diagnostic criteria in reference to symptoms of M.E is exhaustion that doesn't improve with rest. So, scaling back your activity, and using intermittent periods of rest does not improve the symptoms. It is a method using to prevent the worsening of the condition. It does not improve it.
It's quite likely, obviously, and I'm sure many would agree with me, that misdiagnosis is a massive problem. It's a massive problem because it prevents people who can otherwise be helped, from receiving that help. It also has the impact of blurring the actual condition.
People with M.E do get better. People with M.E do die. People with M.E do suffer horrendously for decades. Alone. With no help. Because there are no treatments that have any scientific backing for M.E.
You cannot expect people not to post their personal experiences, and the very real potential reality for sufferers, because others want some positivity, and in not doing so, it is entrenched in their psyche.
I am genuinely glad for anybody whom has recovered from M.E, because I would not wish it on anyone. I'm sure their suffering during their illness, before they recovered, was absolutely horrendous. The simple fact is that there are plenty of sufferers suffering just as horrendously, and in some cases worse, for decades longer, that despite trying any amount of positive thinking and other remedies will not cure. Pointing this out is not jealousy, it's not becoming entrenched with their illness, it's simple fact. I know of people so desperate to recover, they have taken drugs designed for people with HIV. There is no known cure.
