First day of school anxiety

Growing up the night before the first day of school was always full of excitement and anxiety... I never slept a wink the night before. Even when I was lucky enough to get to meet my teacher and see who was in my class prior to the first day. I worried about that one student I didn't know... I worried if the teacher would like me... I worried if I had the right school supplies... I worried if my outfit was cool... Even in college I still had these worries.. heck even in graduate school when I knew all my professors and classmates I worried if I could handle this class... would this be the semester that my inadequecies would be revealed?
So you can imagine that the upcoming start of a new school year is giving me nightmares. Not only am I starting a new job... (what will my caseload be like... how will I do with such a large spanish speaking population... what are my co-workers like... what is the new speech at my old school like?-Yes I still worry about my old kids/co-workers)... but now I am sending my daughter to school... and we all know that our children are a reflection of us. Is she going to make friends? Will the teachers love her as much as we do? Will they think I am a bad mother for my choice of outfit or her unkempt hair? Mostly I just worry about Ashlyn... I know she will be fine. She is an independent little girl. She loves the place we found for her. Last time we went to pay tuition she said bye to me and wanted to go play with her friends...
I really do think this will be good for her but I worry. She's such a picky eater so I hope that seeing the other kids eat will be good for her and she'll start eating more... but as a mom I fear that she just won't eat all day. She's such a bad sleeper... I hope the routine and the activity level will lead her to just crash at naptime... but as her mom I worry she will cry the whole time and the teachers will get frustrated with her. She still has some sensory issues... will the teachers help her or just think she's being a brat? I know she'll be fine... deep down I know it. We chose a good place for her but nobody loves your child like you do... and we have been so blessed to have her home with Erik and/or myself until now.
So I have her bookshelf all ready for school to start. I am well aware she isn't going to kindergarten for everyone who is looking at this picture thinking I am asking a little much of my almost 2 year old but there are lots of pictures of "school" in them so she can get excited!
Does anyone have any books they recommend for starting daycare? Anyone have any helpful words of wisdom for how to make it easier for her? and easier for me???
