It was not easy. However, I really like teaching. I am still stressed sometimes, before my class. Sometimes, I am get blocks but I am able to convey the concepts to the students. They also listen nicely. They may have noticed that I have some speech issue, but they don't laugh or mock me ( atleast not in front of me). I am telling you, we set extremely high standard of speech for ourselves. I also read aloud atleast 45 mins daily. Do some breathing exercises (Ujjaiyi pranayam), do some tongue twisters in English and mother tongue. I am also planning to join local toastmasters club for public speaking anxiety. Believe me when I tell you, that if I can do this anyone can.
