I get different types of physical fatigue which can come and go and fluctuate in intensity. However it is the mental/cognitive fatigue if you can call it that, which is most prominent for me.
The mental/cognitive "fatigue" has been with me for 5 years and has been relentless in that it has never completely lifted. Also there are many different aspects to the cognitive fatigue some of which I had never previously experienced.
The first being an inability to bring thoughts together or losing context. So if I read about "A" and then read "B" which requires I have read "A", I wouldn't be able to bring in "A" and so would have lost "context. (sorry I couldn't think of a better example.
The second is a lack of vividness to my own thoughts or feelings (dysthymia, depersonalisation?)
Third, wired but tired, this often more noticeable when my head is feeling inflamed or when I have exerted my self physically. It is like my brain is very awake but I cannot give it "direction" and cannot focus.
Fourth cognitive actions feel extra heavy or leaden. This to me seems like the brain is inefficient and so something like reading a book or talking to someone feels more laborious than it should. This is one of the symptoms that has never lifted since 5 years ago.
There are more cognitive symptoms such as reduction in spiritual sense (see
Hip's thread) as well as lack of mental stamina, confusion, mental PEM, brain over activity and other strange sensations, which I cannot explain at the moment.
The physical aspect feels like having run a marathon the previous day and/or had a crazy party. Then feeling heavy and leaden. Luckily I'm not too bad physically.
Is the fatigue of ME like the end of a long hard day
I don't think I can get this kind of fatigue anymore, because either I get more adrenaline (wired but tired) or get other cognitive symptoms, which alters my perception/awareness. I would normally associate this as kind of a good fatigue because it would sometimes help me fall asleep easily.
