I used to have the same problem before I came to USA. I still remeber, those few years, specially in the beginning. You exactly defined my problems. My sound used to get smaller and faster. I used to be red, and I couldn't go infront of the class to give speech. As a matter of fact, I requested my government teacher not to have a speech presentation for me, and asked him to give something else for me. Now, I am different. I don't talk a lot to new people, But If I have to, I never mind. All those fears are gone. Few things, No one is perfect. Second, no one  have tim eto judge you,a nd if they do, then what the hell.........They are not in a position to judge you.

Take Rythm Advice as she has degree in phychology and she is right; a brilliant young lady. Take her advice. I always like her words and her input, but still sometimes I have a differnt opinion about her.

One thing, I stiil have this problmes. I cannot talk to a nice looking lady (If i know her i can, but if she is completely new, I cannot) I still ahve this phobia, something like "GergeousPhobia" or BeatufulPhobia". I get red, and nervous and I try to avoid it always. May be thats Why I am still single........
