My son went through a crying period of a few weeks both years he was in preschool. It wasn't even at the beginning of the year! My best advice after doing this we 2 of my 3 boys is to just stick it out. Don't feed into her crying, talk about school being a fun happy place, what she will get to do, what friends she will get to see.
I would carry my son in kicking and screaming if need be. I would tell him to have a great morning, to have fun playing, and that I would be back in a little bit to pick him up. A quick kiss and goodbye and off I went. The longer you prolong the good bye, the harder it is for both of you. And trust me, I left in tears a few times myself. It can be heart breaking. Also, I don't know what the pick-up arrangements are but I always tried to be one of the first parents there so my son didn't worry I wasn't coming as all his pals were going home.
Hang in there! It gets better, I promise!
