I can add something extra to this post. What helped me to boost my confidence, is taking care of myself. - do some regular exercises (gym preferably - because you also meet people with the same goal as you). - dress decent; having some nice outfits can make you feel more confident in your own skin. - eat healthy. It will also boost your morale, because you do something for yourself and confidence will rise up. Many people don’t do it. - make sure you smell nice. Don’t over do it though; stay fresh and clean yourself. - read interesting stuff and learn basic skills. Knowing history, geography, economy will give you points in confidence level. Learn how to cook, learn how to fix things around the house. These also give extra points in confidence. Always look how to become better. Stuttering will be the last thing people will judge you by, because you will be better than most of the people at the other things.
