Enjoy being young, things get much worse as you get older, including your stutter. When I was in high school my stutter wasn’t as bad as now (25). Don’t stress things out. You should join a club or a sport, people in those are forced to talk to you and form relationships. Go out more and join activities. People don’t give a shit about your stutter as long as you have a cool personality. Also People like quiet people more than you think lol.
