Hello Sandi, I did the same things.......it's all quite normal. I even slept in the hospital bed that he died in. The company that brought it wanted to pick it up the next day. I wasn't ready to give it up so soon. I wouldn't answer the phone to them so I kept it an extra 2-3 days.
I know that food is the last thing on your mind right now........But you have to force yourself to eat.
Take care and let us know how the interview went.........thoughts and prayers.......
