I'm not sure if I fully understand what you were asking, but I do think that since my initial trauma I'm more negatively effected by things that have happened to me since. I feel like I've been almost traumatized by things that I probably wouldn't have considered traumatic before.

I have a few experiences to explain how I've noticed an increase in trauma symptoms about other negative experiences if you wanted to read them to see if you relate or anything.

I was sexually abused at 13. I didn't really realize that I was dealing with PTSD symptoms at the time (it seriously would have helped if any of the counselors or psychiatrists I saw told me that part of the diagnosis..) but looking back I see all the signs. I got over that with time basically since I never found helpful therapy.

I was basically a fully healthy (as far as PTSD is concerned, still mentally unwell in other ways) person for a few years until I was raped in January. Since then I've been a mess. I've had some other less traumatic things happen this year, but I've had a few things that I wouldn't have thought of as 'that bad' but they are still bothering me to the point of having some PTSD symptoms over them.

I've had 2 or 3 nightmares now that have been almost traumatizing in themselves and I've had anxiety and even flashbacks over them months afterwards. I've had several nightmares that disturbed me for a day or two after, but left my memory afterwards. Before this year I'd only had 2 nightmares in my life that still make my heart pound to think about (or that I can even still remember after years)

I had 2 miscarriages this year (I swear my life isn't always like this, 2017 was just not my year lol.) and even though I had one miscarriage when I was 13 (before the abuse) that wasn't very hard on me at all, the ones this year have been fairly traumatic for me. I've had nightmares about them, I think about them often. I've had flashbacks about one of them as well. Though, this could also be attributed to being in the family stage of my life now.

These just don't seem like they should be actually traumatic events (although I haven't talked to anyone else about this at all before this post so I could be wrong), but because I'm so vulnerable because of the main trauma I'm reacting to it more than I feel like I would would if that event hadn't happened prior to these.
