I can sooo understand this post. What people can see is me stuttering a little or chattering my teeth. But really underneath I'm grinding my teeth clenching my jaw trying not to nod my head uncontrollably. This is the type of "block" I have. And these blocks started happening in school, in my brains attempt to curb the stuttering. I have had a stutter since I was 5 So 30 years. And the "block" I have had for 20. It will never go away. If I could tell anyone that doesn't have a speech impediment, that we all cannot control this. It is completely involuntary for me. Is mental illness caused by the stutter? Or did the mental illness cause the stutter? Why do we have this shit?
