I've been doing some re-reading of my old posts, too, FS. It is amazing to me how something that I am certain I "will never forget" gets buried like any other thing under the layers of daily life and yes, gets forgotten...
People sometimes think this is "dwelling on" stuff, but there is a difference. If all I did was feel angry/sad/helpless/resentful all over again, then it would be dwelling. If I look back to see how far I've come, or to remind myself of a lesson I learned and need to remember, that is NOT dwelling--that is refreshing my memory in order to go forward even more strongly.
In addition to all the other things I'm grateful for about SR, I'm also grateful for the simple fact that it gives me a written record of my recovery journey, something I'm not sure I'd have otherwise.
