That is what I mean by "shattered". It's also not unusual for one's condition to get worse before they begin to "improve" either. One can survive several traumas and then have a trauma so big that the person gets completely overwhelmed.

We are designed by nature to respond "differently" once we are exposed to something we thought harmless turns out to be something "bad". Or something we believed we could contain and control takes us by complete surprise when we can't or didn't and that something was damaged or destroyed. This can make anyone question themselves, what they knew and their history of overall experience and knowledge.
