how tell fatigue from disease from not sleeping?

my experience of fatigue is that once up on at time rest did help inbetween activity.
over the past few years fatigue has taken over and is now a constant ongoing problem.
i am totally wiped out all day.
every so ofton i used to get serious fatigue that would last for a week or more,could not even get out of bed and my neuro symptoms would be worse.
this was unexplained fatigue and pointed towards ms,but was eventually ruled out.
fatigue for no obvious reason is the type that is associated with neurological illness.

my son says i do snore,i wake up with headache everyday and i use five pillows.
when i have had my appointment for the afo i am going to get the breathing sorted.
it just takes so long to get things sorted at my hospital,my pt was supposed to sort out the afo appointment earlier in the year:roll:.
i need some sticks of dynomite:evil:
