Reminds me of my first job where I worked as a software engineer in a small company. I had to answer all incoming support calls from clients. It was a nightmare! Work at it, you'll be able to slowly remove a lot of that fear and things can get better. I don't think you're meant to cure stutter, at least I don't think that's a thing to strive for. I think the important thing in this lifetime for us stutterers is getting comfortable with it, and opening our heart to life instead of avoiding it.
