When you have a flashback, and realize that you did have a flashback, try and recall what you were doing, what was on the radio, or what someone had just said, or you had just been thinking about, and how you feel. Write it all down and you might begin to see a pattern... good fodder for therapy sessions btw.

They say that once you have had enough therapy to where the flashbacks diminish or disappear, that you go through mourning from the loss of them..they become so "part" of you. I look forward to that mourning time I think.
