After I became a PWSS, I was very nervous to get in a conversation with 3 or more people.However, I realized why should I be afraid. I have the tools now(crutches) to combat my stuttering. Slowly I progressed into conversations until I got comfortable. My suggestions is to read at least an hour out loud everyday. Your mind will hear the fluency coming from you and that will subside most of the dis-fluency memories. Also practice the crutches at home aloud until you know them well. You have the ammunition now so it is no need for fear.
