Did anyone else's voice just lose it's volume

When I was younger I used to be a little shy but nothing crazy I think when I got to like middle school and met my friends that I still talk to daily I was getting louder and louder by the day and you could even call me annoying but when I got to 8th grade I stopped talking to a lot of people and kept to myself half of the time. But when i got to high school I started noticing around 10th grade I stopped talking a lot and with the annoyingness went the volume in my voice type shit, now I always have to say things 4 different times to everyone getting louder each time when I can clearly hear myself the same way I'd hear myself when I was younger but now it's been an ongoing thing and nobody can hear me anymore and I don't notice until after I'm done saying something and I have to really try hard to raise my voice and I don't like talking or being loud at all. I also noticed how people react when i say something and they don't hear me but they just agree anyway and i just let it rock most of the time because I understand but I do like to mumble "you ain't even hear what i said". But anyways idk if it's from some traumatic thing that happened or js something happened to my voice but it's affected the grades of my presentations in school a lot and being shy isn't even the worst part about them now it's mostly having to repeat myself over and over even when I'm trying to be loud but nobody I know had this happen to them i js wanted to know if I'm js trippin
