I'm around the same age and my memories aren't really vivid (well some are). They are more so just clips in my mind, audio bytes that play over and over of people mocking me or laughing at me. The only thing I can say is these experiences taught me to keep fighting. No matter how many times I get knocked down, I always get back up. My stuttering may have fueled that fire in me to fight in the face of adversity. I still hate it though. I feel I need to fight it because I want to be fluent. I can't just let completely go. I need some form of fluency. I need a good balance of fluency and acceptance. Nothing perfect of course but just decent fluency like a mild stutter. I'm more in the moderate range. On a good day though, I am more mild.
