They should be blindfolded and shot. Just kidding, but they dont have CFS/ME!
Psychiatrists should understand you. But they don't even get this. They are frightened if you say this to them. I don't have specific experience have been too level headed trough my live not to say it, even when angry. But I can deduce this from much milder disagreements with them. Psychiatrists generally can't handle what they teach and what they should be capable to handle, not even close. Reason is they don't have long therapy background so they are too emotionally attached to them self.
It's normal to have
thoughts to harm someone who tries to harm you. Its normal to have these thoughts against people you are angry. It's
not normal to act on these thoughts. And generally people suppress these and don't speak of them, but maybe they should. Not in those terms you said, there is too much risk someone not normal will act on them, but milder and more reasonable.
Personally hope everyone who thinks ME/CFS is mental illness gets to experience it through someone close to them before getting ill them self
. This isn't so noxious to them as they can just shed these beliefs away with CBT and GET. And if they can't and find out this is "real" illness, then they got what they deserved.
