So sorry she is going through all that.... do you have visitors in your home often? It could be that it is unsettleing to her routine especially if she is OK once out and about. Most bullies are scared of random, inanimate things but it seems she is just a nervous Nellie. Can you get a trainer or a friend to work with her daily and teach her that things ae OK and not going to hurt her? Treats and high praise when she does not react?
Banks is like this with some thing and it is best to ignore the behavior... if you pet her or talk to her that it 'will be ok'... you are telling her it is acceptable to be afraid.
