Hi Pallavi,
I totally understand what you say. All of these questions and concerns repeat quite often in my mind… but, I have found something which make me believe WE can become effective teachers: I think in academia, people listen to our scientific language more than our English! In other words, how passionately we teach, and respectfully we communicate matter more than how fluently we speak. I am sure you are a good teacher; otherwise, you would have not been asking these questions. Good luck.
