Last month I wrote about avoidance, one component of trauma-related struggles for many people. Another one of the primary things therapists consider when exploring trauma-related problems is what we call “re-experiencing.” When the natural healing process after a traumatic experience does not go smoothly, one of the things that many people will find themselves struggling with is the fact the memories of the traumatic event won’t seem to settle in and fade into the background, instead remaining very charged and intruding frequently into day-to-day life—re-experiencing. ”
