I am no professional but I do not think anything is wrong with you
From time to time with sad things I do what you are discibing of not crying not feeling to cry or be sad- I feel nothing or "dead like" in side.. I sometimes have trouble with information sinking in.
May be right now is not your turn to cry- but do know it is ok to cry and it is good. I know emotions can be hard.
Maybe it is a bit of denial or maybe it is just processing still? I am not sure

I hope someone else can give you better clarification on this- As I said no expert to anything but i do know where you are coming from
