This is where I find kind of accepting it and not fighting it works best. Sort of like emotional freedom technique, from what I understand (you may want to investigate that?).
Basically, just say "Ok, I do remember these things. They were horrible at the time, they're horrible now, and they aren't nice memories. But they aren't going to go away because I'm blessed with a brilliant mind and memory, so I'm going to accept them as they are and not dwell on them. That was then, this is now, I'm going to move on and learn from those times. I'm a better person now, everyone else involved has long forgotten it - it now exists only in my mind. So I accept they happened, I accept I won't ever forget them, but they're just shadows now - they can't hurt me, they're over, so I will move on."
