Hello.
Your description and question prompted me to give you a hug.
I think you were taken aback by the sudden problem and for a moment you were confused—you didn't know who I was, where I was, or what I wanted. This kind of problem is very common. In the course of human or animal evolution, when people usually encounter various problems and are hunted by natural enemies, the most instinctive responses are to run away or freeze in place unable to move because of an overreaction to fear. However, they later remember the seriousness of the situation and act accordingly.
This is normal. There is nothing wrong with it.
Seeing is healing.
My dear, congratulations on recognizing that you are facing an unexpected notice and that you are unwilling to accept the arrangement internally, but unable to refute the other party and voice your own opinions. This is a problem.
I am certain that it is not all because of your classmate that caused your emotional reaction. Some of his behavior has undoubtedly brought you back to when you were a child and forced you to accept reality with resentment. At this point, you can think back to some things that happened in your childhood. Is there someone you often resented but still needed to obey?
Learn to separate the issues.
Someone took a leave of absence, so someone had to fill in for them. This is an objective event.
And when your monitor or study group leader asks you for something, you have options! Why do you have to catch the ball when he can just throw it?
Tell them, "Sorry, this is too sudden and I'm not prepared for this task. Have someone else who can finish the draft tonight fill in."
He can find someone else to fill the vacancy if he wants to.
I believe the teacher was unable to finish the presentation due to illness. I also think this is understandable.
My dear, remember what you want. You are free to choose whether or not to take responsibility for it.
You can achieve healing and say no to others.
If you're looking for a good read, I highly recommend two books: "The Courage to Be Disliked," which is about developing a strong sense of identity, learning to love yourself, and refusing unreasonable demands from others, and "Self-Boundaries," which is about establishing healthy boundaries and setting clear limits.
The book "Self-Boundaries" is also a good resource. It's about boundaries and establishing a sense of self-boundaries. It's important to distinguish your own problems and needs from the expectations of others.
You have every right to refuse someone's request if it is not what you want.
Go into the counseling room and make an appointment. It's free, and school teachers are responsible.
And they are also more professional. You can discuss and explore the problem with the counselor face-to-face and figure out how to solve it.
I am confident that my answer will be helpful to you. The world and I love you!

This is quite a challenging situation to be in. I understand feeling blindsided and frustrated.
I feel your frustration, it's really unfair that you were given such short notice. It seems like the communication from the committee could have been much better. At least now you know, and you can focus on what's next.
It's totally understandable to feel upset about this sudden change. Maybe reaching out to the committee to express your concerns could help clarify things for future occurrences.
The fact that you agreed without resisting shows how caught off guard you were. It's okay to feel angry; perhaps discussing this with a friend or mentor might help you process these feelings.
It feels like the committee placed an unreasonable burden on you. Perhaps you could request some support or resources to help prepare your speech more effectively under the circumstances.
