What if I fall on my face

I’ve hosted my 1st multi day summit back in June and had 20 speakers, 150 people sign up and 5 sales which is a far cry from what I was expecting for sign ups and revenue. I decided to create another summit with only me as the speaker and I launched it today. I’m trying really hard to stay positive around it but its literally destroying me.

My T line is what if I fall on my face yet again
A-Internal stress, negative self-talk
R- anxiety, stress, loss of appetite.
I’m having a real hard time shifting and even being able to create an intentional model or bridge thought.
The fear of failure is kicking my Ass. Thanks in asvance for your help! Xx
