Thank you very much! Your answer is what I was looking for! I certainly will go to Doreen Virtue's sight. As for the little girl, I have tried talking out loud to her and telling her she needs to move on. I've done this twice now. I have called on Archangel Michael for help in other areas but will call on him for this.
My feeling as to why the little girl won't move on is that she may have had a troubled home life. I grew up in a time when kids were allowed to roam the neighborhood but this little girl wasn't allowed to do that. I only saw her when she visited a neighbor's house---and she was only there because her mother allowed her to go only to that house and yard alone. So---I didn't know her well at all. Despite that, I was left with a feeling that we should all walk on eggshells around here. I'm puzzled as to why she stays with me (my homelife growing up wasn't happy either).
For some reason, she doesn't want us to leave this house. Considering just how many times I've moved over the decades, and she didn't block it---this is puzzling!
Again, thank you very much for such a helpful post!
