Should I find a new job and quit my current job since I am not good a public speaking?

I suck at public speaking and I realize that it's a big part of my job as an academic librarian where I will have to instruct students on finding reliable resources for their courses and I don't think I can do it tbh. I thought I could but I'm just not a good public speaker.

And I need to get out before they start making me instruct next semester. So is it a good idea to find a new job and quit this one before the new year sets in?
