Exactly what i thought you meant. But if you can find what causes your stress And social tensions. That is a beautiful thing. Because I personally have no clue what causes mine. Im one of the most confident people i know. Am well read in all all common subjects people talk about. Yet somehow i get so apprehensive when its my turn to speak. So if anything helps to look inside your mind and realize what your issues are. Thats something worth trying. Speech therapy never worked for me. Speaking exercises never worked for me. So this is definitely something worth trying. At least for myself i cant speak for others
