moving day, ping hiding in the bathroom

We move condo last weekend. Ping was very very quiet in the car, I think she is scared of the box and the noise. When we open the new door she run straight to the bathroom and didnt come out for 3 hours. I try to put cat food near but she just look at me from behind the toilet. Another problem is the new condo is 12th floor and she used to be on 4th floor with balcony. Now the balcony has the net so she cant go out and see the birds. She keep sitting at the glass door and stare at the sky. Very sad face. I bought the cat tree from Lazada and put near the window. Now she sit on the top and watch the birds next door tree. Is better. Vet said give it time, one month maybe two. I hope so because I cant take more crying at night.
