It took me into my late 20s to realize that I had a traumatic childhood. The thing is I did not grow up in a poor or abusive household. I grew up in an upper middle class family that looked extremely normal, and for a long time believed it myself, until I started wondering why I had since jr high felt acutely depressed, empty, and unable to hold on to meaningful relationships. Only a few years ago did I realize that both my parents were emotionally neglectful and did not validate my emotions at all growing up, and did not act or behave in a way that seemed like they were even aware that emotional care and validation of their child is at the core of good parenting, and not just feeding them and putting a roof over their head.
It explained a lot about how I act today, and why I became very independent at an early age. I continue to struggle with feelings of emptiness, depersonalization, emotional numbness. It sucks to feel like you cannot escape your childhood even as a grown adult.
