My experience was close to that. A year and a half on I still sometimes wake up from nightmares about it. But it gets better.
My initial response was deeply rational, like me personality type, and I tried to analyse every little thing.
The truth, I think, is that in the end, the universe is ambivalent. Life goes on.
I have a post it note on my wall which I refer to often: "#1 man rule: I'll be fine". Men need to remember we're men, and we'll be fine. We are tough.
