How long with it take for a 7 month old to adapt to a new home?

I left my husband yesterday (found ANOTHER sexual email to a DIFFERENT person... some just don't stop) and my daughter has been so fussy the past 24 hours.... I am at my parent's house and my father was offended when I said she didn't like it here. But when I meant, nothing is familiar. She sleeps in a pack n play, instead of her crib. It doesn't smell like "home". I had a difficult time feeding her today. And whenever I leave a room, she freaks out. Never has that happen before.

I am so tempted to go back "home" because she's acting so bad, but I know I wouldn't be happy. How long will it be until she's comfortable?
