awwww. it'll be ok. my cat was left alone several times and I moved with her (20 hour on a plane and such. 2 hours in a car.....when we got here there were like 50 people waiting for me and she got so scared) I felt terrible and thought she'd never be okay again and she'd be so traumatized, but she's really ok now.
she really clings to me though. she follows me around and makes it very clear to me that she doesn't like it when I leave the house; when I get home she's always waiting for me by the door and the minute I sit down she gets onto my lap and stays there for hours.
she also sleeps curled up against my belly every night. she's my baby.
your cat will be ok
