Awakening,
Your post made me feel better! Harassment is definitely significant and yet you still forgot about it. I know that my forgetfulness is not just about insignificant things.
Sorry Rachel, it wasn't my intention to make you feel bad. But your question seemed to be about remembering specific dates and lengths of time, not specific events. I would find that to be exceptional trait for anyone, PTSD or not. I hope you didn't take my post to mean that your life hasn't been significant or something like that.
I remember when I was in grade school I used to ponder this a lot. I would think that today is not out of the ordinary, so I won't remember it next year. Then I would think about how who I am today will have been forgotten by the person I will be 10 years from now. Strange, perhaps, but it turned out to be true.
When people ask me what I did a few days ago... if the day was structured or out of the ordinary I'll remember it... otherwise I'll struggle until I look at my calendar and realize that I didn't do anything worth remembering on that day. That's what I meant by that, some days aren't anywhere near the life altering level. A lot of my friends are the same way. I just chatted with one online:
me: can you remember what you did last thursday?
friend: no clue
me: how about yesterday?
friend: yes
me: saturday?
friend: yes
me: if you felt an emotion last week, can you remember how long you felt it for?
friend: nope
me: I don't remember what i did last thursday either
friend: if i went back and looked at my calendar and had something on it, i'd prolly remember but off the top of my head, i remember very little
Anyway, I hope that helps make this less scary for you.
