I’m actually planning on joining Toastmasters after Christmas ! I’ve had a stutter since I was around five also, and it did hold me back in life a lot. I’ve heard many great stories of people who stutter joining toast masters and it helped them gain confidence speaking in front of a large group of people. Everyone is there to listen and help each other so do not worry that you will be judged! - everyone is there to work on themselves :) definitely go for it!
