Angel, It sounds like your little doll has separation issues. Take baby steps, and try and distract her, like during day, leave her in a room, just for a tiny bit, with something she really likes, either a bone (I like the Nylabones) or a treat, or her favorit toy. Start with just going outside the door, close and before she has a chance to start her show, go in again and praise her. Keep doing stuff like that, just the smallest amount of time, and then when she seems okay with the few seconds you probably think are rather pathetic, make it longer and longer but take baby steps, and patience...... . Lots of it.
I am sure she will get better even if it may take some time before you get to sleep in your bed again lol...... Good Luck and please let us know how things are going.
