I am guessing what you mean by a third world country in Europe. Romania? What you are describing, playing outside alone, was completely normal and commonplace. I grew up in the former Soviet Union and I started using the elevator alone when I was 6 and going outside to play, unsupervised. I attribute much of my independence to those early experiences. You are framing your life history as "managing" to thrive "despite" what happened, but have you considered that you "proceeded" to thrive "thanks" to having spent your childhood in unsupervised play with your age peers? If you read literature on child development, you will learn of the importance of unstructured play.

What happened did lead to your father taking decisive action. He actually confronted, found the perpetrators, did everything to find justice. That involving the police probably was not harshly consequential for the rapists was due to system set-up at that time and not to passivity or inaction on the part of your father. Have you considered thanking your father for believing you and for taking immediate action to punish the people who wronged you? Not every parent would do that.

Your parents raised you in full conformity with thr mores and customs of their country during that time period. Life is not without risks and you found yourself harmed because your parents did not practice what is now called helicopter parenting. But you also reaped enormous benefits thanks to the fact that they did not act overprotectively towards you, stifling your development.

The rape might have led to far more negative emotional consequences for you had your parents disbeleived you or played down what happened. They did not do that. Their response was congruent with reality and reaffirmed for you the sense that you were an innocent child who was violated. This was huge. This is something to thank them now for, not to cut them off over. You can read many accounts of how parents react to reports of sexual violence coming from their children to situate your parents' reaction on the continuum of possible reactions and finally appreciate they the y did very, very well.

If your son's birth led to resurfacing of those memories, it is an opportunity to revisit what happened in a conversation with your parents and expess your appreciation for everything: their reaction to that specific incident, their moving you to this country which provided you with opportunities to do so well, and their current involvement with their grandchildren.

Based on what you wrote, your tendency to go to extremes, you are at a heightened risk of becoming an overprotective parent yourself now. Having grandparents actually helps you avoid that trap (which can seriously disadvantage your kids for life), so your parents are an asset in your life, not a liability.

I am glad you posted to reality check what would have been an absurd step that would have deeply harmed too many people to name, including you.
