New shift

I have been working afternoon shift at the same place for almost 5 years. I recently changed to day shift. I feel lost! I don't have a routine down for days yet. I feel intimidated by this and I feel like a total looser. Anyone ever feel like this before. Some of the day shift aides are pretty nasty. I feel like they dont want me on this shift. I had to change shifts for family reasons. Any advice would be appreciated.
