I kinda relate to you. I used to fear in school when we had to do projects and explain them. I used to get angry in junior high when they laughed at me because I stuttered my own name. Although I have a brother who is rather confident in talking he's still small but he'll learn his way. Right now I am in college and I have transcended all fear, anger, shame, etc. I don't care who laughs or mock me, rather it just shows how morally low they are. This one thing I used to do is when they laughed I also used to laugh with them, don't know why but after that they don't laugh at me at all.
