Yeah same with me...I was also super talkative before the stutter got bad. I think it was okay up until the middle of highschool when it took a drastic turn for the worse. Like even in grade 8 and grade 9 I was still somewhat chatting away. These days it takes soo much effort just to speak...it just gases me out and takes away any joy from chatting with friends and family. I think it definitely has something to do with puberty I heard autism goes full power during puberty so that might be it. Man I remember talking on stage to the entire school in grade 7 or grade 8 but nowadays I wouldn't dare do that. Blows but overtime I have gotten used to it somewhat.
