What I do is I talk to Delilah all the time, greet her each time I walk in the room. I try to keep her feeding time and everything at a certain time, so she knows she can trust I'll take care of her. If your room is safe and/or you have a fence, you should let her run around, interact with her. Give her a treat every so often, even if you don't feel up to taking her out of her cage, just stick your hand inside and talk to her. They like to know their loved.
