Stuttering Help: Fear of Telephonic Conversations?

Stuttering Help: Fear of Telephonic Conversations? I have been having my fair share of bouts with psychogenic stuttering since more than 10 years now. One of my fears, which apparently so plagues me every day has to be the fact that I very much tend to avoid is to avoid speaking to people over the phone (telephonic conversations) When I put some critical thinking about why is it that i do it, I sort of come to the conclusion that it is deeply rooted in the fact that I have had some past memories of disfluency. And that i think talking would lead me down the same drain. How do i overcome this mentality. Any help would be appreciated
