Why? Is this CD?

Why is it that I can read other people's stories here and have such a horrible reaction to the way they've been treated? But when I read my own words I feel numb. It doesn't seem to affect me like it does when i hear about what others have gone through on this site. It almost feels like watching the same scary movie 1000 times, until you get to the point where the scenes no longer shock or disturb you. Is this normal? Why aren't enraged about the way I have been treated?
