Happy birthday Belle! 
I think you're right about accepting the illness. It is NOT the same as giving up. It is just learning to work with what we've got. :)
I have hit a wall today (metaphorically of course!) - I think this weekend will be tough, I'm working tomorrow and DH is on Sunday. I was fine at work this morning, had a great time running our baby singalong session, and was then clearing up when BAM it hit me like a tidal wave. It is scary how quickly the fatigue comes on isn't it?
The rest of the shift was a struggle, and then I had to pick up the DCs at 3 but we went to the playground (very near) - at least they are old enough to play on their own so it's not too much work now, and totally worth it to tire them out a bit and assuage my guilt about them not getting enough exercise! I got DH to meet us there too and carry their stuff home which was helpful.
Interesting about the immune problem. I have read some things to that effect and it did make sense. I really hope it comes to something - while I do think (IME anyway) a lot of health professionals are coming round to the idea of ME being a physical illness, it certainly isn't filtering down to the general public yet and I don't think it ever will unless a concrete explanation is found.
Too tired to read the link tonight. I have been having major trouble sleeping lately, nowhere near what some of you have to deal with though. I haven't felt this depressed for ages (purely because the physical illness has been, in some ways, a distraction!) - the other day I actually felt 'too depressed to work' IYSWIM - I did go in but despite feeling physically well I really didn't want to, I just wanted to stay home and wallow and cry about how shit my life is! My short term memory is declining at an alarming rate too. I have no idea whether I've been missing my Ami or taking double some nights. Need to start using my pill organiser thing again.
In other news... I only found out from mum as I haven't spoken to dad for a week but my nan's biopsy results showed lymphoma :( apparently it is very treatable so it's not a dire prognosis but I guess it depends what nan wants to do.
On a lighter note - wanted to share this big bang theory quote which sums up how I think myself to sleep (or attempt to!) - I run through lists.
Howard: Please, I'm begging you, go to sleep!
Sheldon: I'm trying, I'm counting catwomen!
:o
Sorry for the essay, really must try and sleep now!
