Confidence is a product of success, and success breeds more success. I've been teaching high school for 18 years with a moderate-to-severe stutter. That literally didn't happen over night, it's the result of an [ongoing] process. Start cultivating a habit of taking on attainable challenges. Order takeout on the phone instead of the internet. Strike up a conversation with a stranger [or a cute member of your preferred sex]. Call instead of text. Volunteer for something that requires you to talk. **Success isn't having perfect (or even typical) speech**. That's just not going to happen. Success is being willing to do something that's difficult (but attainable), even if you do crash and burn in the middle. Success is realizing when you do crash and burn that it really wasn't all that bad (ie. no one lost a limb, hopefully). Once you score some wins, you'll find it easier to tackle other challenges. You'll find that you start thinking about your stutter differently. You also may find your speech improving. My speech is always better when I'm in a good head-space.
