1-1 meeting

I want to do well at this.
I need to well at this.
Each day, I'm afraid that I'm going to lose my job, because I'm not doing enough, or not being thorough.
I'm just always afraid.
I want to do well, and I want these kids to learn. But, I feel out of my league...constantly.
What can I, a 25 year old (7 year college graduate) teach these children?
It seems so incomprehensible and uncertain.

I need this job for my family and my son.
I need it like I need water and food.
My family needs it like water and food, so they can have water and food.

There is so much riding on it, so much to be done.
