When I was four I'd automatically cry when punished, even though I didn't cry when hurt, and I've never been burdened with a sense of guilt for breaking the rules(which was a long-winded way of saying I was autoprepping to be beat), when I was 5 I was interrupted when trying to kill myself(nobody found out because I just heard someone coming so i had to hide). Ever since then my temper has always gone from 0-100 instantly, panic same way, everything 0-100 in an instant. I don't know if those are actual symptoms, but I don't recall much change between now and then besides the environment :p.
Oh yea, hypersensitivity, my watcher. I can't help but keep track of every person within sight or hearing. Now that I'm tired I don't keep as sharp track, but I used to have a photographic memory, and I'd keep obsessive tabs on everyone. I can still feel people if they are in the same room. Like, I don't know how to describe it, it's like a buzzing under my skin in their direction, and the closer they get, if I'm not comfortable, the more it spreads and prickles.
Wherever I go I'm always thinking about escapes and weapons in case something goes wrong, as a kid trying to sleep in my room at night, all the shadows and clothes and everything would start to move and change shape. Again I don't know if that is under ptsd
