Boy, isn't it great being a new parent ?
This is separation anxiety... I know that when I first got Kuma, I used to hate leaving him because he was alone all day but my Mom kept telling me that you have to leave him alone so that he gets used to it... He cried and barked for a bit, but now, he's almost pushing me out the door. ( I think he has parties when i'm gone
Try leaving a radio on or the tv on so that she hears voices.Make sure that you give her toys so that she can play with and keep herself busy while you are away.. Crating is NOT cruel, it will keep her safe while you are away and give you a peace of mind...
Good Luck
