My memory is something of the opposite. I've had an avoidant personality most of my life and this includes my memory as well. I just don't seem to form very strong long term memories of bad events. You could say that's a good thing. I suppose it's certainly better than being haunted by bad memories, I'm sorry you seem to be, but it has some pretty big negative down sides. For examples I had a horrible time all through school from K through grade 10 when I dropped out for a year, 11 and 12 were good. As a result I really can't remember much of anything from all those years. It's kind of just 10 years or so of foggy uncertainty, and unhappiness, punctuated with a few sharp moments here and there. But there were times years before when I was much happier, but much younger, that I remember as sharp as a tack.
