['I have a huge presentation at work this week. I have never done this before and I am not sure if I am prepared yet.', "Oh no, well I'm sure you'll do okay if you just prepare really thoroughly.", 'I still have a few days to prepare. It will be in front of a new potential client. I really hope it goes well.']
I hope so too, good luck!
I have a huge work presentation coming up Friday and I am very nervous.
