This is pretty frustrating as 90s-kid who had a Good Childhood™ and struggles with interpersonal issues. I have a close friend from childhood who also had quite a Good Childhood™ and he can't shut up about "trauma" and it seems like every two years he has this big epiphany about how he addressed some "trauma" he was previously repressing and how now that he's done so he's All Better Now™. His behavior and overall life outcomes do not have any correlation with these epiphanies. Both of our lives absolutely pale in comparison to the lives of average children in previous generations in terms of 'trauma'. Minimal bullying, no fights, always plenty of toys and food, loving parents, etc.
I know some people with real, legitimate trauma (verbal and physical abuse) and they said that visiting a therapist really helped them to feel a lot better. In such cases of legitimate trauma, I agree that one should do something about it if it's making you feel bad. However, many of those people were already. interpersonally excellent before and after 'addressing' their trauma.
I have had people (including the friend from the first paragraph) suggest I need to "work on my childhood trauma" but really and honestly I can't think of a single thing that was legitimately traumatic. I could take my worst experiences, which I have moved on from and don't feel any need[0] to think about, and inflate them, but I'm pretty sure that would be creating a new psychological problem.
[0]I don't feel any hesitance to thinking about them either. I can sit and ponder them for a whole afternoon if I like, without emotional fluctuation. They're just memories.
