Although my stutter has gotten better since I finished school, I've certainly become a very shy and reserved person due to teasing and the like while I was at school. There were honestly days there where I wouldn't say a single thing cos it was guaranteed at least one person would make fun of it. I'm happy to be out of there, and while the stutter may not be as bad nowadays, I think my shift to being a quieter person could be a permanent personality change.
