I use to grieve for the "old" me, spent several years feeling angry and sad about how I was so changed by it all, wishing I could go back. Spent years trying to answer the whys, and wondering what if it had never happened. Now I guess I just have a different perspective about it.
Life doesn't stand still, everything including me, is constantly changing in some degree. Even if the trauma had never happened to me, I still wouldn't be the same person I use to be back then before my trauma, today. I might be married to someone else, had kids, lived somewhere else, who knows what experiences I would have had differently, that would have changed me in different ways for better or worse than who I am now. Maybe I wouldn't even be alive right now had my life path been different, and I never experienced my trauma.
When I look at things in this perspective, it makes it easier for me to not feel such a loss for someone I wouldn't be now anyway, regardless of if I had or had not experienced my trauma.
