It gets better - I promise. How old are you? If you haven't tried this - seriously read aloud for 30 minutes a day. At first, you'll stutter but you'll discover that you'll get into a 'flow' of fluent speech. It's hard to explain unless you've experienced this. You'll hit this fluent 'flow' more often the more you practice. Doing this will absolutely retrain your brain to speak more fluently. Try it - I believe in you!!!
