shylah there are a few coping skills that can help you and your Master:
It sounds like this girl's problems have become the family's problems. She has been through a difficult time and you and your Master are to be praised for being there to help the girl. The important thing now is to stop the chaos and establish a few things NOW.
Make a list of issues that are causing trouble and also a possible solution. Then ask to speak with your Master privately. Tell Him it is important for you to speak with Him if you are to help the other girl when He is not around to guide you. You have questions that need His attention.
I'll take from your post here and start it:
1.) "girl # 2" is always worrying that someone is angry or has issues with her. she goes to other people in the house to ask about it. While it is good that she is concerned, it makes us each speak for the other person, which is uncomfortable. I propose that in the future, when she asks if someone is upset with her, that we suggest that she go TO THAT PERSON. If we stop speaking for each other and trying to placate her fears, she will realize that her fears are groundless.
2.) "girl #2" seems to need reassurance with even small tasks. she either forgets how to do them, or needs help when she shouldn't. I propose that in the future, I will show her how to do something no more than twice. After that, I would like to be allowed to refuse help until she masters that skill on her own. That might mean that she serves You burnt eggs or forgets to iron Your shirt for work. If You would prefer not to be inconvenienced in this way, my only other suggestion is for her to not be given tasks that directly serves You until she proves that she can do other household tasks without supervision. While i am preparing Your eggs, She can wash dishes or sweep the floor, or something else that frees me up to serve You.
A list of issues should not be a list of gripes about all she's doing wrong. It should be a GAME PLAN where you discuss a problem and suggest a solution, so that your Master is not overwhelmed by having two unhappy slaves.
You might also include in that list an few things you appreciate about her. If she is a good cook, or if she has a great nose for bargains, or if she has a number of useful skills or hobbies, MENTION THEM and incorporate her strong skills into the household so she feels useful. Have a GAME PLAN - I cannot stress this enough. Possible ideas:
1.) Master, girl #2 is wonderful with a sewing machine. Perhaps she can do mending in her spare time or make those curtains for the living room that I've been wanting?
2.) Master, girl #2 does a great massage. Perhaps I can assign her to run Your bath and attend You on special evenings? (Caution, this can turn sexual, so don't make this an every night unless you want her to get His sexual attention and you be left without on a number of evenings)
Ask your Master what specific areas He wants her trained in... focus on those and you will see whether she really wants to be part of the household or whether your home and family is just a bandaid for her.
If you and your Master are working together, HE will see that she isn't working out if she doesn't take full advantage of all you do for her.
