It's very important, at 22 years of age, that you're careful with how you speak to yourself. You are not a complete bum. You are a valuable person, and you have valuable thoughts and valuable things to give to the world, just like all other people, despite the fact you have a stutter. When I was your age, I too was very nervous and very conscious of how I presented myself to the world. Every pause, which was 5 seconds, felt like 5 minutes. But it's important to know there's a huge difference between the perception of ourselves and how other people actually see us. Don't give up, be positive, relax, you've got this.
