I used to wear a nice big thick rubber bnd on my wrist and when I would get caught in the mode of analyzing things from the past, I would snap it (and I do mean {i}{b}hard{/i}{/b}).
Looking at these things for patterns to my own behavior was one thing (and actually helpful), but I know you know exactly what I mean about getting "caught up" in that mode.
Since my D's are getting older now, I have alot more "free" time on my hands. I've taken to meeting up with groups of people that have the same interets I do. It gets me out and keeps me busy (ok, I am really more than busy enough, but I find the social interaction has been critical for me). Perhaps you could find something similar where you are.
