Rights of servants

Q: Please guide me specifically in matters and in which conditions we discontinue our relations with our close family members like parents, brothers, sisters, wife's relatives and even Muslim brothers and sisters. 

Q: What is the ruling regarding a person who's parents have been unfair to them and continue to do so? How should they maintain such a relationship with their parents as it hurts them and makes them upset with their parents all the time?

Q: I have alhamdulillah started doing shar'ee purda by covering my face, hands, feet etc. I have stopped talking to all ghair mahrams e.g, my classmates.

1.What should I do?

2.Is this be pardagi permissible in anyway?

Q: I have a best friend and when she was young her mother always used bad words or would curse her saying "Go and eat so and so pooh". Presently she feels that because her mother used these words, her life is miserable. She always struggles in life with work and even with her proposals. Whenever she gets a good proposal, it breaks up and she feels guilty because Allah Talla accepted her mothers curse. She even helped her mother whenever she was hospitalized and financially. What is the Islamic way how on how a daughter should be treated? What would be the status of the mother on the day of judgement and how can my friend overcome this situation? She always repents to Allah for these curses.

Q: Are you sinning if you disobey your parents if you refuse to marry who they want you to?

Q:

1. Is straightening with one's legs stretched out in the presence of  one's parents haraam?

2. What if this is done on the presence of an elder?

Q: Allah Ta'ala commands us to join family ties. Who exactly falls under the term family? Are one's in laws included in this command as well?

Q: Is there any hadith regarding the brother's and sister's huqooq (rights)?

Q: I am very depressed even though I pray salaah five times a day and sometimes I pray tahajud too. I read Quraan 3 or 4 times a day. I think that I am disobedient towards my parents...

My mother always wants me to study but when I open my books I cant focus. Moreover I have applied for a job at the bank but when I open the books to study, thoughts come to my mind that it is haraam and Allah will punish me. My mother wants me to work and I am very depressed.

I make lots of dua and offer nafl prayers too. I ask Allah to help me so that no one will be displeased with me.

Please advice me so that I can come out of this depression.
