I stutter for as long as I can remember, one of the first stuttering moments I can recall was on an end of the year kinder-garden presentation, there were close to 300 people staring at me waiting for me to talk, I froze for a few seconds and then I spat it out. But it got worse over time, as I got more conscious about my stuttering, and it's at it's worst when I speak or read out loud in class...When I know I'm about to talk my heart starts racing, when I'm blindsided by the teacher I stutter the hardest part is to say the first word. Two days ago I got some heart and chest pains while I was talking and trying hard to talk, it got progressively worse over-night. So I did an ECG and it showed that my pulse is around 100bpm, I instantly figured out what's wrong: I go back to school tomorrow and I've been dwelling on that and it feels as if I'm in the damn classroom about to talk, the doctor gave me some beta-blockers but they don't seem to work. I'm sure my anxiety is the main reason why I stutter, If I can forget for a second that I don't stutter, I'm positive that I won't. I'm 17 by the way.
