Mo, this was bound to happen. You have been running on adrenalin and energy for a long time. Your reserves have been used up. So you now need to restore them.
First, long bath, with smellies if you have them.
Next coffee in the sunshine, If any.
Next, two kitchen chairs, blanket over them, and a rug under them, in the garden or sitting room,for the dcs to play cave men, campers, explorers, mugs of milk and biscuits out there.
Now, on your bed, your privacy, go on to Gutenberg and read. Old free classics, like Pride And prejudice, little women, soothing music, drift off.
Say nowt to ChainMo till you are more rested. .
Hugs
