alt Hacker NewsYou don't grow out of it as much as learn to manage it, this requires that you develop some form of executive function though. In my case I was forcefully required to be responsible for my younger brother (when I was 7) and so learned out of necessity -- but this led to a lifetime of resentment and so I don't recommend it as a solution.
I was homeless by 16 and had no safety net, had to graduate high school on my own while living out of someone's garage, and generally take care of myself most of my life due to absentee, drug-addict parents, and I can tell you that this trauma only worsened my executive function by the time I had the privilege of being able to sit back and reflect from a place of security and comfort.
I'm sorry you have resentment issues... definitely get that.
