amen dude. Im totally convinced my stutter (and many other's) is an anxiety/psychological issue. For some like myself, I dont stutter at all when no one is around and that to me is proof that there's nothing wrong with any part of my speech mechanism. Its all about whether or not I feel calm/comfortable. One trick I've been using lately which has had good results is focusing not on how to produce sounds but on the tone/rhythm of how im speaking. This takes my mind off of trying not to stutter which as we know makes it worse.
