Seek help and guidance where you can. Getting back to speech therapy is a big one. I can't say I share the same level of anxiety do to my stutter. I work in research, so speaking a lot varies day to day, and speaking to customers is unlikely. The fact is you have to push through it and face it. Work with your therapist. I find my stuttering has cyclical periods that are bad. Your speech may have atrophied due to not having to combat it as much. Stutters I find adapt very well, because most of the time we have no choice. Move forward always, and learn to forgive yourself.
