I wasn't always a stutterer. I just had small bouts of stuttering here and there as a child but nothing too serious. In fact, many people go through a small period of stuttering in their childhood. My speech was normal just like everyone else throughout my childhood. Even though I am an introvert, I never hesitated to speak in class to contribute towards a lesson or to do class talks as part of some activity. I could talk to anyone confidently. Things changed sometime in 2005 when I started high school. At the beginning of it, I was fine but then my stuttering came back and it gradually kept getting worse. I'm now far worse than I was 5-6 years ago. This has severely hindered my ability to talk to people. I have trouble with pretty much every sentence I say. I want to say more but the words don't come out and I end up saying yes, no, something really short, or even irrelevant. I do force myself to talk as much as possible whenever I have to like making important phone calls or helping out a lab partner and so on. This is mainly because I'm tired of shying away. But just trying so hard puts a strain on me at times. While I would like to become fluent again like my younger self, at this point, I just can't see it happening. I'm still adjusting to a lot of things and trying to better myself in certain situations. However, you're right that there is frustration in having a part of you taken away.
