At the breakfast table my head bowed and my eyelids almost closed. I understood that this was just another day when I didn't have any other choices then to follow my body's needs, even if I had other plans. I crept to bed for half an hour.

I think that the most important when such "things" happens is to accept that so it is. It would be a big mistake to start self blaming.

I am on my feet again (without self blame) and am ready to fulfill my to do list for this day.
