I'm 19, I've got a few problems that are annoying me:

  • My voice cracks once a day, to the amusement of others
  • I speak too fast and am asked to repeat myself often
  • My voice isn't very deep
  • I stumble over words occasionally
  • If I don't speak for half an hour (eg the commute home) my voice cracks when I start speaking again or just sounds weird.

Is this a confidence issue? I feel confident am bulking right now in the gym. Any advice?
