Have you looked into renting a place with some other female friends? If you ask around, you may discover that there are other friends who are stuck in a similar predicament (wanting to move out of home but not having enough money to rent a place alone).
You must keep up with your education, but I fear that if you continue to live in this household, it will suffocate you. Your parents currently hold a huge amount of power over you because ultimately they are putting a roof over your head. However this roof comes at an enormous cost to you (and it is too dear); make no mistake, after uni, your parents will likely start to put an enormous amount of pressure on you to marry and produce children (and this pressure will never end until you completely cave into their demands).
You are adult woman, intelligent and capable of making your own decisions and choices. And you have every right to. Life is for living. Your family may be your family, but that doesn't mean that you have to be family towards your family (especially if they aren't treating you right). You need to save yourself.
Personal experience/angle of my perspective: I am not religious, however I grew up in a very controlling and abusive environment in which my mother constantly used and abused my sense of family loyalty (which she instilled in me) to control and manipulate me into being passive (despite all the bad treatment). Nothing ever made her happy, and despite constantly trying to manipulate me using my strong sense of honour, she herself was one of the most self-centered/sabsorbed and least loyal individuals I have ever known.
I was a good kid (working hard to bring home good grades and be helpful around the house etc) but if anything, the harder I worked to try and be worthy of decent treatment in her eyes, the worse she treated me. There were also all the usual manipulative arguments of "What will the people in the village say" (we lived on a farm) etc, but in reality this was just another way for her to justify her control and mistreatment of me.
Eventually at age 16, I had enough and moved out of home. And it meant that I quit college and started working full time. I moved out with a guy I had been dating for 3 months, and we are still together to this day (this year will be our 16 year anniversary together!). The early years of independence were full of trials and tribulations, but it was so COMPLETELY worth it!
The day I moved out of home, was the day I began the journey of living as a truly happy individual.
At the time, the only reason why my mother allowed me to move out of home so young, was simply because she thought that I would fail in my attempt (and she was looking forward to punishing me and making my life a living hell when I returned). But my attempt was actually 100% successful (I never moved back home, never became homeless and I never looked back).
Initially I completely quit contact with my mother (intending to never speak to her again after all her horrible treatment etc) however after about 6months, she start creating pretexts to pressure and persuade me back into contact with her. And in the end I caved in, as I thought that now being fully independent, I would get to call the shots in the relationship more (and so would not be so vulnerable to her manipulations etc).
However unbeknownst to me at the time, this fateful decision to reignite contact would start a new cycle of miserable back-and-forth relationships with her (with me desperately trying to create a mutually respecting normal mother-daughter relationship and her constantly throwing away chances that I gave her, deliberately trying to hurt me and constantly trying to manipulative me etc). I still longed and hoped for a normal relationship with her (and she knew that and took advantage of that longing). The death of my wonderful father when I was a little girl, also intensified my need for a parent.
Fast forward to over 10 years later, and I finally decided that if I was ever to truly enjoy my life (which was very blessed by this point), I had to remove the dark cloud that constantly cast a background shadow on it. And that dark cloud was my mother. 10+ years of trying every approach with her, a 1000 chances given, and she was still not treating me well (she would try to manipulate me against other people with outrageous lies, tear down my self-confidence etc).
And so I finally cut off contact with her (for good).
Despite everything, it was still an extremely difficult decision to make at the time (and one which I had doubts about even as I made it), however cutting her out of my life completely ended up being another one of the other best decisions of my life that I have ever made. Again at the time, she didn't take my threat seriously as she thought that I would cave in and let her back into my life. But I stuck to my guns on the matter 100%.
The present day: These days I am significantly happier.
There was another negative family member that I cut out, and other the years I have lost a lot of remaining family due to death.
So sometimes I do feel a sense of loneliness over family.
However I am also a lot better off, having reconnected with more more decent family members (finally finding some of the good family that I longed so much for). And I also exercise a lot more quality control on friends, so that although I have a lot less people in my life, the ones I am surrounded with, are just such more significantly positive and supportive individuals to be around. And being surrounded by such better quality people, I have finally overcome my "demons" of the past (my bouts of depression, stress, anxiety, insecurities etc, all being left far behind now). I'm a much stronger individual these days (taking on new things with a lot of confidence etc) and the future has never looked so bright!
So I would say:
Value those who treat you well (and distance yourself from those who do not).
Focus on doing what you need to achieve your dreams, and do what you have to do to protect yourself.
Family may be your family, but that doesn't mean that you have to be family with them all. For people who do you no good, you need to draw a line somewhere.
Its a fools errand to try and please everyone (as there is simply no pleasing some people).
Don't sacrifice your happiness for other people's sake's.
You deserve decent treatment in this world (and those people who you have to fight to be treated with decency by, are not worth it).
Be prepared to make tough decisions and actually follow through with them (sticking to your guns on matters that matter to you).
Plan carefully and make sure you have backup plans for when/if things go wrong.
Create your own support network of decent friends, wise teachers and better family members. Having decent support and counsel, will make a world of positive difference in the upcoming challenges ahead.
