This describes perfectly how I experience symptoms.I'm kind of seeing it similar to having a back problem. A sudden move can cause a twinge and reignite original symptoms. You heal it again. Fine for ages. Until another sudden move.
Alongside that, acceptance of trauma having been part of my life has helped me accept myself more and accept the strengths I've developed because of (not despite) trauma.
Before that, I used to fight against it and always wound up feeling like I'd failed to get over it again and again. That just reinforces negative cognitive distortions. Part of that distortion was how I imagined healed to be and I think that's a necessary consideration for your question.
