Selene, I absolutely know what you are talking about because before SHTF in my case I thought that things like that happens only in some strange countries, somewhere far away.
It is in human nature to not expect things like that to happen, especially if someone is not experienced that before.
Now i expect anything.
And funny, but I used similar “technique” when I had really really bad times during the SHTF, maybe some kind of fatalism, or similar, my emotions were suppressed.
Yea, it helped me, but on the other hand all emotions from that time came back years later and hit me like a train so…
There is no easy way to go over some things, but point is to GO OVER it, to survive.
