Greetings,
It is bewildering, it is scary. Present-day life experiences and markers trigger a flood of recall and unsettling partial memories of trauma are doubtlessly hitting you with full-force now, and as unbearable as it is and seems - this is the stuff of P.T.S.D. and better life quality beyond the disorienting now.
Your in a storm of sorts as threads of different repressed memories likely somewhat inchoate are surfacing, whereas seeing a trained trauma therapist will allow you to receive vitally-needed validation concerning all that went on and help towards the organization of a narrative. Know that the now white-hot sensitivity felt now, that combination of extreme pain and vulnerability felt will slowly lessen in intensity for the deliberate process of taking ownership of it - as difficult or impossible as such is to fathom in the moment.
No - the sensitivity to environmental stressors and the tendency to traumatically recall in my experience doesn't go away, but the response can be better-informed, better-trained, and understood to the extent that life quality improvement can be secured. Flitting back and forth between reasoned calm and outright despair frightens me terribly, but we must each labor to extend out the good periods. You feel terrible - but you've also been afforded input and feedback consistent with validation that what you suffer is real - and this is a start. The present moment is a start - please have faith in this if nothing more.
M.K.
