This really depends long-term. Not everyone that experiences trauma develops PTSD, but at least speaking for myself, I've had a few decades of hopelessness, helplessness, and a lot of general emotional immaturity for my age. Particularly since so much of it occurred when I was a kid and heard the line about being mature...I regress to that childish mindset often in my 30s still. It's taken a lot of effort to develop the social support I've needed in conjunction with therapy and education to even start the process of actively healing rather than just surviving.
