Recovery does not mean cure. Recovery is an attitude, a stance a way to face daily challenges.
Well, that's not really true, according to how it's generally understood. Recovery means that you get over the illness and are healthy again, so it's closer to "cure" than anything else (the main difference being that "recovery" can be spontaneous, whereas "cure" implies treatment). If a recovery isn't complete, it's known as a partial recovery or remission. You can have the best, most productive attitude/stance in the world and still experience deterioration in your illness. The thing is, a lot of people decide that they are going to improve their attitude and do the best they can, and some of them think of it as, "This is the start of my recovery." For the ones who actually recover, I can see how they would end up associating the two very strongly. It doesn't work that way for all the people who find that they're still ill, they just have a more positive attitude. Indeed, insisting that someone is recovering when they are visibly deteriorating is highly unhealthy psychologically. We also tend to be very jumpy about this because we have all been told by well-meaning people that if we just think positively and eat more fresh vegetables, we will recover. ME is a serious neuro-immune condition which is not curable by positive thinking. The people who give us this advice generally go on to blame us if we don't accept it as a heaven-sent cure for our illness, and accuse us of wanting to be ill and even of making ourselves ill. Does that explain why people have been getting so upset?
I get that you found that you needed to make a profound attitude shift, and that focusing on the negative is something that really doesn't work for you. However, if you want to be active on a forum about illness, there's quite a lot of negative stuff that comes with the territory. You may find it easiest to restrict your activities here to the more social parts of the forum, if the heavier stuff bothers you. Plenty of us do, as there's only so much illness talk you can immerse yourself in and still keep your head clear.
Meanwhile, I'd suggest you clarify matters on your blog a little, if you want people in the ME community to read it. (And you may decide that you'd rather keep it as a private thing for the time being.) Explain how ill you are and were, what the illness was like, more about exactly how the treatments worked.
You may find it useful to learn more about what severe ME is like. I'm afraid it's not true that anyone with ME can benefit from tai chi or yoga. Anyone who is severely affected (and this forum has a lot of those, perhaps the majority) is unable to do anything like that level of exercise, and struggles with the amount of exertion needed for basic washing. Moderately affected - not quite sure how it works for them, but I do remember going to a very gentle yoga class when I was moderately affected, and being wiped out for the next three weeks, so it's likely that even the moderately-affected folks can't manage it either. Exercise intolerance is the hallmark of ME, remember.
In fact, I'm trying to think of anything you can say will be good for everyone with ME. Apart from an improvement in symptoms, e.g. we could all do with better sleep (but the path to better sleep will be individual), I really can't think of anything. Lack of stress, perhaps. That's not really a treatment, is it. There are certain areas most of us find it useful to work on, such as sleep, nutrition and so on, but even so, nothing is universal. I think you have a lot of lovely ideas, you just need to contextualise them better, and to understand how they read from the perspective of people in this forum.
