When I was your age, I was exactly like you. My message to you is: it will get better, I promise. I am 48 now. I still stutter sometimes but I am able to lead meetings, present research papers, raise a kid, etc. It is still a struggle that most people around me cannot see or understand. But I accomplish the things in life I wanted to accomplish. And yes even now I often feel like: fuck it, I will just quit talking. But... the world would not give a damn. Hang in there and don't worry, ok? And about that girl: if you like her, next time you see her, smile at her. It makes wonders. And if she does not like you because of your stutter, great, it least you know she is not worth it.
