Have you made it a sudden change from being accompanied d to having bbfish staying in the bathroom wth door shut?
Perhaps you can make it a gradual transition.
Start from having the door half-shut leaving a big gap, with you/or maid sitting next to the door but within bbish's sight. Answer bbfish whenever you are called.
If bbfish is OKay, have the door almost totally shut leaving a narrower gap. You still stay next to the door to answer bbfish whenever called.
Next, have the door really shut and you 'v got assure her that you can hear and you do answer whenver called.
