I had horrible anxiety throughout high school and we used to have to read aloud during English classes, in turns, usually from a book.
In one English class, whilst my voice was breaking during puberty, my voice broke and went from deep to high pitched and everyone burst out laughing.
I also had the job of masking Tourette's symptoms during high school, but when I did let out some tics, people noticed, including people I had a crush on & it was embarrassing.
