((granite)) this is something to learn and not something you have to already know.
It's something new and unknown, 2 things that can trigger fear easily.

Do you think your T is setting you up for failure (and subsequent getting rid of you)?

You can't fail. You won't have to learn it before you go and you won't have to learn it all at once. All you need is your willingess to learn. You'll be learning at the pace that fits you. It's something that is interesting and that takes practice. And as you practice you begin to reap the benefits.

You are scared, but you can do this and being scared .
