I can empathise. Im clinicaly knackered myself, ME/CFS, another managed untreatable condition.
Like having the Flu constantly with varying levels of pain, feeling knocked out,limited mobility and brain fog.
Had it for about 15 years now but had to give up work as a web developer about 5 years ago.
All the help you get is how to handle it and make the best of what youve got and try to stop the de-conditioning of your whole system.http://www.afme.org.uk/allaboutme.asp?table=contenttypetwo&id=1
Apparently there was an ME/CFS awareness week a little while ago unfortunately no one told anyone about it.
Im playing with Arduino, Linux and Android to keep my brain working since Ive had to give up work.
I manage a few hours a week when my concentration and memory arnt too bad.
Cant do the spannering I used to enjoy on my vehicles as I havnt got the strength or stamina.
I manage to work on my motorcycle a bit as I have a bike bench to lift it up to a working height.
But the Landrover hobby has been put on hold indefinitely.
But sitting at my bench with all the kit to hand I can get some real pleasure from knocking something up. As long as I dont loose track of the time Ive been working, overdo it and spend the next day or so recovering.
Let the clinically knackered unite, were not completely useless.
