I went through the same thing! My first time doing a presentation and I talked so much without breathing I constantly had to take in massive gulps and nearly passed out.
Tbh I think mostly everyone in your class will be going through the same thing so just take comfort in the fact that you’ll be presenting to many understanding people.
I don’t know if this will help but I found a stress ball and put it into my pocket, I clenched it and let go through the whole thing and it seemed to take my mind off it. I find that in the most stressful situations that if I have something I can fiddle with it can take my mind off what I’m doing.
Remember to breathe, talk clearly and make eye contact with the people you are talking to! One of the worst things is having your eyes on your cards and only imagining what people’s facial expressions look like. Better yet when you stand up find something to look at, like a centre point, look at your class but always find your way back to a certain point when you feel yourself getting worked up.
Practise, the more you know about your subject the easier it will be and try not to think too much about it when you’re not rehearsing.
Try the stress ball, a scrunched up piece of paper, present to family or friends, talk to a classmate who may be feeling the same. Concentrate on the elation you will feel when the presentation is over.
If you make a mistake or get your words mixed up, laugh it off. Remember that the audience will be going through the same situation as you and that they won’t judge you for feeling the pressure.
I hated presentations, it was the worst part of my course so I can definitely feel your pain. Don’t back out! You’ll feel worse when it’s over, get it over with and add to your presentation experience! The feeling of seeing it through and beating your own insecurities is the best! Good luck!
