Teddy is my first pup and I am crate training him. I'm sure others can help in this area too, but perhaps you should crate your pup and keep her den in the room with you? I know some members have bought the snuggle puppy, which is battery operated and imitates a beating heart and emits warmth. Here's a link

The puppies are sold out, but you can buy a snuggle kitten it is the same.
Anyways, the point I'd like to make is that I think you are going to have to train your dog to be independent, and enjoy spending time alone...I think crate training her is a good start and as she does better then you can give her access to larger spaces, more rooms in the house etc. I also recommend that you watch this video, it will provide you all of the advice I've read other members give, except you will get to see it in practice.
