What are the origins of insecurities?

  This article is a direct continuation of the previous reflection on the invisible impact of childhood. If that one explored how certain traumas shape our personality without us even noticing, here I want to focus on another side of the past: how certain experiences - no matter how small they may seem - can take root in our insecurities, affecting the way we see ourselves and how we relate to others.
  The topic came to me because of a very specific episode that, funnily enough, happened when I was only eleven years old. Back then, I had a "girlfriend". We were behind the school building - the classic meeting point for little couples at the time - and after a kiss, she gave me a compliment. I don’t remember exactly
what she said, just that it was something nice… but followed by a comment that has stayed with me ever since.
She started talking about her “ex” - who happened to be my friend and classmate - and said she had never kissed him, because she preferred to kiss me. The reason? Because I had nicer teeth.
  At the time, what should have felt like a compliment quickly became the seed of a possible insecurity. My friend had a genetic condition that affected his teeth and voice. What bothered me most wasn’t just the fact that he was my friend, but the way she spoke about him with a sort of disgust, as if his appearance repulsed her. I never told him anything, because I knew he already carried enough for being different, and hearing that from someone he had been with would only make it worse.
  The irony is, I had crooked teeth too. Not as noticeably as his, but more than the “standard” of everyone who had braces. And even though it had never been a real issue for me until that point - truth is, I used to avoid photos, but that was just part of my personality back then - with time, that insecurity grew. I started taking more photos, but never smiling with my teeth. Years later, I realized that small experience might have left a bigger mark than I thought. I wore braces for several years, and today my teeth are one of the things I like most about my appearance. And yet, I still don’t know how to smile showing them. Not because they’re unattractive, but because I hid my smile for so long it became automatic.
  All of this leads me to a question that still puzzles me today: are our insecurities something we’re born with, or are they planted by others? Or do they come from what we think others see in us?
  It’s easy to assume that our fears and doubts come from within. But do they really? Or have we, like me, heard certain comments over the years that - even if unintentionally - stuck to our skin?
  Maybe we’ll never know with complete certainty where each insecurity began. But it’s worth reflecting on them. Questioning. Understanding that, more often than not, the roots of low self-esteem lie more in experiences than in logic. And maybe, by recognizing that, we can take a step toward a freer, more self-aware version of ourselves… one that truly belongs to us.
And you… do you have any insecurities? And why does that bother you?
