Had the same issue, this book changed my life: The Charisma Myth. Be warned though, the book has lots of exercises and if you really want to improve/change, then you need to do them and work hard at it. It will take a lot of effort and time. You can see the effects very quickly, but to really do things automatically without thinking about them, it might take years. A lot of the stuff in the book is based on mindfulness. You basically first need to be very aware of your emotions, then get comfortable with them in any situation. Once you are comfortable with your emotions, dealing with everything else becomes a lot easier and fluid. Also, this tedx talk has some great advice about seeing self-confidence as a skill you can develop through practice and positive reinforcement: https://youtu.be/w-HYZv6HzAs https://youtu.be/w-HYZv6HzAs
