I know I know I was a lot stronger when I was younger too.
Even a decade make a difference. I asked my councillor recently howecome I'm have such a hard time now with this stuff, while I managed to get through way worse? Sounds to me you have your wife through good and bad years. I always found the best thing to do is to talk open about the feelings of fear. I found often they turn out to be mutual or just my perception. My councillor and I concluded age has something to do to with it (but then that goes for everybody). An older friend said we also get wizer, more resillient that way, so use it.
I cannot go to my father for advise anymore either (he was my commander). Even from a far while he was still alive, I had a voice in my head. It told me what to do when I was in danger, when I had to fight. When he died the compass started spinning, I lost my North and that voice disappeared for a while.
I've also found that there are people in my life that are sort of parent figures. My mom is still alive, but I even have a mother figure here too.
The I could have done this, I could have done that, when you go through the sequence of event's can drive you pretty crazy. You didn't know, didn't expect it, so why would you have wondered about the sound of the bullets ? This was the same time you didn't know he was anything but a happy person. Plus you were a teenager ( the brain is not fully grown, thinking concrete and not abstract).
People in general are afraid to loose things.
I feel the same way you do about this forum, now all it takes is someone that knows about walls,ceiling's and ice to respond ;).
Your trying to make your 'dreams' true, so watch 'suggestive' dreaming ! I read in someones thread on here, how they think about happy things before going to sleep helps.
