Old memories

Today I ended up recounting the events of March 2008 to one of the girls at work. I found it VERY upsetting and ended up in tears. Not floods of tears - really not much more than moist eyes - but enough to remind me how much I am affected by these memories. Part of me thinks I should be immune to it now. Part of me thinks I should be over it. It worries me a little what it means that the memories cans till affect me so much. I either need some therapy - or some meditation to help me sort out what I need to learn from the situation - then I can hopefully move on.
