I highly recommend finding a hobby that doesn’t involve talking - for me, that was music. It’s twofold in its helpfulness: you get to share something cool with the world without speaking, and you have an activity to fall back on when stuttering gives you anxiety and hopelessness. You’re 17. As you get older, you will come to accept your stutter more. Confidence will begin to build, and you won’t let your stutter control your thoughts as much. Best of luck!
