I have insane blocks mostly when I start a sentence. I went to a phone carrier booth to get a new deal and ask about the plans. I went up to the booth: "He said hey, how are you? How can I help you?" I have my mouth open and nothing was coming out for like 20-30sec easy, man I was trying soo hard. That dude just stood there waiting for me for 20-30sec and didn't say a single word or change his face expression. Man I can never forget that. Some of the other things friends tell me is that I dont even notice or I dont feel anything or its fine. It doesnt matter. Gives alot of confidence
