Hi Jill,
I'm so sorry that you are feeling unnerved! You can check out our Reliability Support site to receive more assistance and for more resources. As for the videos, for your second attempt you will have another set. If you are still struggling after your second attempt, contact our Reliability Support Team to set up a 1:1 Zoom meeting so they can assist you before you start your third attempt.
Let us know if you have any other questions!
