Nah mate you should encounter me at 7am. I is a mean mamma then!
You're in an adrenalin fight or flight loop Lucky, and it's utterly knackering. Your brain races and races to fill its self up with thoughts - to avoid pain - and then can't go on anymore and you hit the emotional wall. All the hormones leak out of your eyes, and in sweat, and you are left utterly wiped out. That triggers the race again, as the brain can't face being still and being able to think....and on it goes....
It will all slow down, I promise. But this is a pretty brutal part of it and very jarring and jagged.
I'm known for this bonkers advice of mine, but low lights, soft fabrics, gentle mushy food, quite sounds - these will help. It's hippy and true. People who experience post traumatic anything will talk of the bright lights and harsh sound and temperature. And you have undergone trauma, although I don't suggest you or anyone here has a posttraumatic stress disorder. But we can learn from this experience of others. I feel.
Have ranted on for ages, when all you really need is you and dh wrapped in a warm blanket and a box of soft tissue. Hang on tight to him, this too will pass. x
