When I was younger, I did wanna just ended because it wasn’t fair that others spoke fluently and I didn’t. I thought it was a curse being smart but yet can’t even say my name or hold a conversation without people looking at me like I’m dumb. Eventually as I got older, I just stopped caring and started talking to people and start working jobs that require me to step out my comfort zone. I still get blocks here and there when my anxiety kicks in and I can’t even get a word out but I just breathe in and I’m okay. Your speech is something you have to work on and see what’s best for you. You can waste money on speech therapy but those tactics may not work for you. The more you talk, the more you realize what cause you to stammer so much.
