A lot of these comments have a great advice, but as a fellow 17 year old who has also struggled socializing with kids, I think I can provide some advice. The biggest one for me was working on myself and trying to find my identity. I found passions in music, fitness, politics, and a lot of other things as well. Finding these little outlets to explore and not having to worry about speech related things helps you feel that sense of fulfillment that’s often lost when stuttering as a teen. It’s hard, but start by watching YouTube videos in anything that vaguely interests you, and use that as a launching pad to explore more. Secondly, as others have said, talk as much as possible, but I take this one step further. Here’s an example. I get drive thru food a lot, and often times I stutter a little bit when ordering, saying thank you, whatever. The workers don’t care, but I’d be lying if I said it didn’t get to me a little bit. Use those opportunities away from your peers to work on speech strategies. For example, when saying thank you, I try to look the worker in the eyes when I say it, or I add “have a goodnight man” or something to push myself just a little bit.
