Here’s what I can tell you, straight up dude, everyone knows you stutter. Embrace it! I know it seems scary but, if you’re not a dickhead yourself you can make friends. Being quiet sort of makes you less approachable, how I started to be more out going is answer questions. A majority of the time I knew the answers but I was to timid or afraid to answer. Answering can seem nerve racking, so ask questions. Asking was always easier because you can rehearse it in your head and raise your hand whenever you’d like. As appose to waiting to get chosen to answer. This would raise my confidence especially getting acknowledged for answering the question correct. You can also talk to your counselor about getting speech therapy sessions which I regret not doing. Don’t worry I’m sure they’ll keep it on the low
