I'm delivering a speech to my class this Tuesday So I am failing in my English class and my teacher is giving me a chance to get a passing grade by just delivering a speech in class and I have some problems. And getting that failing grade would make my life miserable.

Problem 1: I am not allowed to bring my exact speech with me in a paper (I don't know if I can bring a manuscript with me) because I'd be reading only.

Problem 2: I have a lousy class. My classmates are too noisy they just won't behave. Or if they would behave they'll make fun of you.

Problem 3: Whenever I speak English I feel uncomfortable or I cringe I don't know why I feel that way maybe it's because I'm bad at speaking in English or it's just English is very sophisticated compared to my language or maybe I'm not confident because I'm not used to talk a group of people in front of me.

Leaving your thoughts in the comments would really help me guys because I really like to give my teacher a real speech.

What's the difference between 最初, 初め, 初めて?
