I once choked during an oral presentation but was told it's okay just take my time and I was able to get all the way to the end of it after that I received some applause from the audience too. I felt special.
It can be difficult and intimidating at times but rest assured eye contact can make your audience fall in love with or be disinterested in your oral performance. Always try your hardest.
Ive never made eye contact with anyone ever in my life but people still think i have GREAT eye contact. Look at their nose or mouth or just to the side of their face. Then it looks like you are making eye contact but really you arnt. Its a win win
