Probably too late for this but...
For 15 years I avoided presentations at work. I would even let others take credit for my work because I was afraid to speak in public. I would be shakey speaking in front of just a handful of people sitting around a room. There then came a time that I had no way out. I was forced into giving one and I was nervous for 3 months prior. I did well and it gave me confidence for others. I gave more and more and each time I got a little less nervous before and during. I now sort of enjoy the time I'm speaking in front of eveyone (I would never have predicted that in a million years). I still don't volunteer to give them and I get nervous and overprepare before them, but I am able to do what I never thought I could.
Do the presentation and realize that you're not prepared but understand that public speaking is a common fear and you're not wrong to not want to do it. Be brave and know that you don't ever look as nervous to others as you think you do. Speak up, look around the room, take deep breaths, take your time, engage the audience and you'll be better next time. Good luck!
