Why does my 2yr old act like this?

my daughter just turned 2 on may 24 and also just started daycare for the first time may 23. I used to have an in home childcare but decided to go back to a daycare so I'm right down the hall when we are there. at home she sleeps with me and my husband at night but at daycare they fall asleep on cots by themselves. it seems that ever since she started she throws a fit over going to bed at night. she will scream and cry and try to get up and this last for almost 2 hours until she gives it up. by then its 10 and then she now decideds to wake up at 6am when she used to go to sleep at 830 and wake up aroumd 8am. when we get home after work/daycare she will scream and cry over any little thing we do and this lasts until bedtime and in the morning she will wake up fussing, for some reason she'll want to change clothes and she'll cry over what breakfast I'm fixing, what she wears, she cries like crazy when I drop her off in her room too. what can I do to fix this???
