Seeing that you are very young and haven’t stuttered your whole life I can understand your frustration, I was the same way but I’ve stuttered my whole life. At 25 I’m lucky enough to have married someone that has helped me become more comfortable with my stutter and not being ashamed of it. When I was younger I used to get so frustrated that I would dig my nails into my own skin or literally hit myself in the head. I felt so stupid that I couldn’t speak fluently and I hated the looks people gave me when I would stutter. I can’t speak for everyone but I feel like most people aren’t saying “deal with it“ in a rude or giving up way. I feel like it’s more “except yourself”. Maybe one day there will be a cure or one of the tricks or therapies will help but in the meantime be kind to yourself and except yourself.
