It’s ok, we will go very slowly, because I’ve also been working through all these fears myself. The book is paced slowly so that you have a better chance of being able to succeed. So no worries, we will do this, and we will create a safe space for everyone to learn.
I agree that it takes a lot of courage however, to face the unknown. If I get some time I can post an exercise that my new teacher gave to me to do. It can help you with the fear.
