It wasn't really a well-known condition a few decades ago, though i think many veterans suffered from it, they just didn't know what it was. I was diagnosed with PTSD but not from anything war related.
In fact it's mostly from night terrors related to something I experienced as a kid, but not anything to do with my home life. I can't really explain it (and it's better if I don't) but I still deal with it. It started as a kid when I was about eight, and I'm not about to turn 65 and I still cannot sleep in a darkened room or any room with a doorway facing the bed.
I can't explain that, it would be useless to try, and the one person I did expain it to said he was having trauma now also and wished I'd never told him about what was going on. It's like planting a seed, sharing these horrors and that's something I don't want - I just have to deal with it the best I can.
