This would have probably done more damage. :(
I laud your honesty and the courage to share such a powerful story. I have such shameful incidents in my past too. I remember being mean to other women because they weren't fair, rich, or got good marks in exams!
Though we can never have that time back, the least we can do is open up about such issues so people who are of similar age and have access to the internet can read our stories and learn.
After all, reflecting on past mistakes and working consciously towards never repeating them is a wonderful way to grow. :)
