This is compounded by a type of OCD I have (diagnosed) where I feel compelled to remember events exactly as they are and how I felt. Crikey, if I remembered all the things that caused me guilt/regret I would have no time for anything else. You have to move on, but in a constructive way of course.

Also, are you sure you are remembering them exactly and not putting a slant or emphasis on them that makes you feel bad? You have not done anything a court would condemn you for after all.
