I'm sorry I was mean, I had an awful morning. Look man, you're being too hard on yourself. You can't expect to get every job you interviewed for. Keep trying don't give up. I used to have an insanely bad stutter, and I have still been able to pass multiple interviews in my time. This weak overly conscientious attitude is a problem, I had that for years. Its very limiting. You have to have confidence, even if you do stutter it doesn't matter. Don't let it bring you down. I get a bit angry because I see my past self, wasting mental energy worrying about (stupid) things like that. You can do it
