Thanks so much for this, I really needed it man. I having the same feeling when pronounced the S and T/P sounds, it feels like I hit a wall and cant continue to speak properly. I get the paranoid bit, I am little different there. I know I have it and its always there, but as soon as someone mentions it I shell up. Even with people I know won't be dicks about it. I don't even deny it. I try to come out of my comfort zone, I play soccer but I find myself being being introverted and not participating vocally like everyone else.
