I never thought I'd be coming to reddit about this, but I really don't have anyone else.

I have a presentation next week which I feel like I physically cannot do. I feel ill and like passing out when I even think about it.
When talking in front of large groups, I can't talk or can barely say a few words.

I don't know what to do. I would usually ask my teacher if I could do it after class, but as this is in groups of two, I'd feel too guilty to cause any inconvenience to the other person.

I just don't know what do and hoping that someone here could give me advice on what to do. Thanks. :)
