We ask Allaah to compensate you with the best of that with which He compensates His slaves who are patient, and to expand your heart, and to make things easier for you, and to improve your relationship with your family, for He is All-Hearing, Ever-Near.
With regard to your forsaking your sister, if that is because she is doing something that goes against sharee’ah, and your forsaking her will achieve some purpose for you, by keeping you safe from her evil and harm, or it will achieve some purpose for her, by influencing her and making her give up her sin, then there is nothing wrong with it.
But if it is for some personal reasons, or for some difference of opinion over some worldly matters, such as some family problems, then it is not permissible to forsake her or cut off ties with her. If you greet her with salaams, then you are no longer regarded as having forsaken her. That does not necessarily mean that you have to spend a lot of time with her or talk to her a lot, especially if such contact will not serve any purpose for you or for her.
We advise you to try to get to know some good and righteous women by attending gatherings of good women, such as classes to memorize Qur’aan and the like, so that they can be a good help to you in doing good, and a means of warding off this introversion of which you complain, and so that you may benefit from their knowledge and activities.
We also advise you to try to benefit from your free time by listening to useful tapes and reading useful books which will increase you in faith and knowledge.
With regard to the servant who is falling short in her work and mistreating you, there is nothing wrong with you rebuking her and disciplining her in a manner appropriate to her misbehaviour and in a manner that will improve her, without transgressing the limits or harming her.

With regard to carrying a book of du’aa’s whilst praying Taraaweeh, there is nothing wrong with that, but it is better to try to memorize some of the du’aa’s and recite them during your prayer. This is more conducive to thinking of the meaning of the du’aa’ and not moving too much whilst praying.
We ask Allaah to help you to do that which is good and to keep you away from evil and its people… Ameen. Praise be to Allaah, the Lord of the Worlds.
