Thank you all for this thread. I had thought that obsessive-compulsive self-exposure to triggers was due to my trying to break through the traumatic amnesia only.
If only I had a dollar/pound for every time this forum makes me say "the only reason this happens is PTSD" (not my PTSD, not my life, just PTSD in general). When the 4 F's: Fight/Flight/Freeze/Fawn defensiveness is triggered, which for PTSD, is a great deal of the time, taking it easy and moderation do not compute.
Thanks for posting and helping share this concept. With practice, I think we figure out ways of breaking out of the 4F's, whether that involves avoiding common triggers, or exposure therapy. Working within a window that does not narrow life, into a total triggered state nor a running from life, that is tolerable is best.
It is easy to overdo things as a survivor in an attempt to help oneself. (Over-correction?)
For me, what has helped most is to have stopped hiding all this and to have a supporter to offer reminders of when I'm trying to do too much. Not hiding myself or my PTSD has been the largest hurdle.
When I'm spending large amounts of time on the forum, or doing any kind of "work" that he knows can trigger or exhaust me too much, he knows I'm just trying to grow. But he invites me to join him to do something else, so that I don't let myself go it alone too long.
