My brain does not function as it should.
It should tell me that right now I shouldn't be focussing on getting ready for IMUK. It should tell me that I need to relax and focus on (a) my sister who is expecting her firstborn and (b) the stress that I'm experiencing in my own life. But for some reason it isn't kicking in. And its probably the reason why I am sick. Because your body can only take so much and no more.
I didn't run the London Marathon.
On Thursday evening I came down with severe stomach cramps and illness and for a good few hours I was permanently in pain and sick and losing anything that I tried to put in my body, including water. After having very little sleep on Thursday night (if I got 1 continuous hour, it was a lot), I, in my infinite wisdom, decided it was a good idea to go to work... which got disproved 20 minutes after I got to work because I was still sick and the smells of breakfast and coffee in the office didn't do anything to help how I felt.
So I went home, filled out the tick box declaring that I needed to withdraw from the London Marathon due to illness and instantly fell asleep. My form got sent off by recorded mail and I should receive a 'Illness and Injury' entry to next year's marathon, but its not particularly something that I'm proud of. I felt like the world was not on my side and felt incredibly sorry for myself for the remainder of the weekend, while I was lying on the couch and as I was watching the marathon on Sunday morning. I was supposed to be there!
And this morning I'm still ill.
I know I couldn't have run. There was no way that it was going to work out with me not being able to eat. Can you imagine running a marathon with no nutrition? But I still wish I could've run.
Now, before this pity party becomes much longer, I'm going to pop off and do something else.

Take it from me, throwing up during a marathon is miserable. You did the right thing.
