Traumatized

So my beautiful little 7 year old started 2nd grade today. She has been at a semi-private school for 4 years now and this year is starting public school.
I got time off of work this morning to drop her off, things went fine. She looked terrified, she doesn't know anyone (neither do I for that matter). I walked her into her classroom, she met some little girls and boys there and her teacher then I had to leave. We said our goodbyes and love you's and as I walked out I broke down crying. I didn't realize how hard it would be for me. I guess I have kept her in a protective bubble since my divorce and now we are starting to branch out. I know it is good for her and for me but tht doesn't make it any easier. We told her she needed to remember what she did today so we didn't get the "I don't remember" answer when she gets home.

We'll see how things went later!
