So here's the thing,   Whenever I want to say something to my friends, or recite something in class, I feel scared and the words get caught in my throat. For example, when I have something to study and recite at class, I spend a lot of time studying, when I come to class, my mouth gets locked up,  and I start repeating every word and everything gets scrambled up, then I end up with a bad note.   Another example is, when I have something to say to one of my friends, I just don't know what to say. I'm really good at inventing what to say in my mind, but when I want to say it I just can't.   Any help on how to overcome my fear will be really appreciated, thank you!
