Thank you all for the replies and advice.
I can only get the help of an islamic scholar if my parents aren't so scared of being "shamed" in the community. However, I will try for that later on.
Tomorrow at noon, there is a meeting at noon between my father, my sister, and a private counselor that I found. My sister admits she has anger issues and she is going under the guise that these issues will be treated. I am hoping and praying that this visit will have some positive effect on her and will make her see that what she is doing is wrong and will develop a level of understanding in her.
School starts September 7th and she thinks that she will get to go the school that she wants (we'll call it school A) because she threw a fit in front of the school counselor. But that school is full, and she will have to attend the school that is literally in front of our house (school B). Yet she says she will "die" before she attends school B or gets separated from her friends. She will go for homeschooling before she goes to school B. She has even listed School A on her facebook page as the Class of 2014. So it will be a huge mental shock for her when she realizes she can't go to school A. My father knew that she would be going to school B since june, but still never told her because he said he wanted to avoid a fight.
A big part of me hates my father for what he has done to my sister. I know it's wrong for me to feel this way. But my sister could have been a normal, responsible , and sweet girl had he not "babied" and spoiled her all the time. There is always a "back door" for her out of every situation. He can't say "No" I'm fasting, I can't take you today. He can't ask the question, " Who are you visiting?" Why are you buying that $80 jacket? WHy do you wear punk clothes? WHy do you always have to have the volume on MAX at your radio station? Why do you bang the car door? Why do you always cuss ( say f*ck, c*nt, b*ch,etc.) He never enforced any rules on her, and then my mom just gave in as well. She maintained a good relationship with my dad because he always gave her the option to do whatever the hell she pleased. He just says that this is the only way to "save " her as if she isn't listened to, she will committ suicide. He says counseling might make things a little better, but she is a serious mental patient. I am afraid she will end up killing him one day if she doesn't get better.
In January 2010, my dad had to leave for Pakistan for 2 weeks. THus mom was the only authority in the house. Things were a lot better between mom and my sister, they would bond more and talk more. I honestly feel as though my sister had a better demeanor when mom was around. Now she calls mom a B*tch whenever my mom asks for simple things. What i wouldn't give to go back 5 years... Alas, we can never go back in time. Time gone never comes back no matter how much you want it to.
I know in my heart that if my dad worked to his full potential (which he did prior to November 2007-when my sister really got bad), he could be very successful and happy. Perhaps he could have spent a little more time with my mom who is also going through menopause.
Honestly, I'm in my room studying all day ( for my MCAT on 09/02/2010) and I don't feel like coming down for iftar because my parents will fight or there will be some sort of obscenity coming out of my sisters mouth. I just pray to allah (swt) from the bottom of my heart that my sister gets better, she assimiliates into the norms of Islam/our culture, and our family problems get better as it is very sour at this point. No matter what happens, I still love my sister and I want her to be successful and a good muslim. I want whatever is bothering her to go away and for her to control her anger.
Please continue to keep us in your prayers. Also pray that tomorrow the meeting with the counselor will yield good results that will put us in the right direction. I know that if she is untreated/nobody tells her the wrongs of her ways, she will eventually really go away from this family and not associate with us at all. It is already painful enough that she is either in her room, outside, or away from us whenever we go anywhere.
I pray that alllah(SWT) blesses everyone with happiness, wealth and peace, iA.
Blessings,
Ehsan
