Hey there!I feel that is a common reaction. Something comes up and demands our attention, which is hard to garner. It probably is adrenaline or related type of reactions. It overrides the Sickness Behavior for a bit of time. And the AD situation, also common with us.
If the "something" arises when we are badly crashed, things could turn out badly.
And I'm describing people with ME who can get up and move around some.
I thought at one time I had Lack of purpose fatigue .
And while I was seeing Dr's I figured I might as well have my Mental state looked at too.
So I saw three different therapists
The others were second opion and third opinion.
They tried some of those mind altering drugs but they did not help me!
My Dr put me on PristiQ and to me it did not feel like it helped, my Wife told me it does, she says I am more laid back! I told her if I get any more laid back I would be in a coma!
So basically I listened and I am still taking it.
I always ask her to keep an eye on me when I am taking new medications and to hide the bottle if I start acting strange , because I might not be able to realize the change !
