I'm pretty sure that I developed stutter because of social anxiety, not the other way round.

I'm pretty sure that I developed stutter because of social anxiety, not the other way round. Hey everyone, I have really good memory. I tend to remember stuff since when I was a kid. Before joining school at the age of 3.5, I was a really outgoing kid. I always smiled, and was really bubbly in nature. I was comfortable with random guests coming to meet us. Then I joined school, and I got really asocial in general. And, ofcourse, I developed a really tiny stutter. Like, I started fumbling on 10 words a day at max. I never really cared about stuttering. When I started to grow older, something was different in me. I was super asocial. I never uttered a word with strangers, except at school. For example, in our culture, greeting the guests is really common. I never did that till I was 16 or so. Even with my close cousins & uncle/aunts, I never spoke. Idk why, they would want to speak with me, and I would reply with fluent response, but always to the point, 3-4 words sentences. I never socialised with them. Everyone would look at me weirdly because I never talked, unless someone asked me question. Because of my "mute nature", my parents were embarrassed of me throughout my life, because our culture is all about speaking & socialising with guests. And, for the main part - my stuttering was pretty much non-existent during this time. I thought about stuttering about once per week, maybe, or even lesser. Then I changed schools when I was 16.5, and I changed from "hardly a stutter" to "above mild stutter". I couldn't speak my name during introduction periods. When I started stuttering more, I didn't think any of the stuff I wrote above. I just thought, "I''m stutterer since birth, nothing new". But that was false. I wouldn't compare "10 words per day stutter" to "hundred times per day stutter" with blocking on my name. And, boom I'm 24+ now. I think about stutter hundreds of times a day. Most stutterers say that they became anxious because of their stuttering, but for me, I have always been socially anxious, and asocial, in general. So, could it be possible that I'm stutter because of my anxiety? Also, one important detail - there's a neighbour living next to our home, he has severe stutter. He never tried to hide his stutter, and he's really loud. My parents & neighbours have constantly made fun of him. That neighbour is the only person I know in real life, who stutters. So, it could be possible that I related my general fumbling to stuttering? I'm really emotional person. I don't stutter at all, when I'm alone. So, can anyone relate with me? /End. I'm kinda bad at writing stuff, so please ask me any details, if you doesn't understand something.
