Feeling nothing, numbness

Yesterday my 4 year old needed to go to the hospital for a possible head injury. While in the hospital I was shocked at how I felt – nothing. Dead inside. Totally cut off. I have tried to model this but have not made traction

C – E at hospital
T – I feel numb inside.
F – numb
A – be kinda overly calm, robotic, quiet, maybe unresponsive or unsupportive??
R – I continue to feel numb

Not sure if numb should be a t or f or both. Help is most appreciated, thanks!
