How long has this been going on? You said since you moved into your new house, but I didn't catch how long ago that was.
Have the vet check her for mites or skin infection.
If she was used to being in the bedroom by herself in the old house, and now is in not only a *new* house but in a room with lots of activity, that could be stressing her out. Certainly the move stressed her out on its own.
Do you normally have lots of sound going on while you're working? The radio, the tv, possibly porn videos or something? The noise that she's not used to could be bothering her.
Normally birds thrive being in the room in the house that gets the most activity and has lots of interesting things going on, but if she was accustomed to being by herself in a quiet bedroom, this could be a MAJOR change for her.
From the looks of her feathers though, I doubt you'll get much improvement even if you do get her to stop plucking. Once they're bald, they're bald.
PK and Pink have given you *very* good advice, about the only thing I can add is to take into consideration how much you can make her new environment seem as much as possible as her old, comfortable environment that she was used to.
That and give her lots of love.
