Broken thoughts never mend

SO it comes to this:
My life is going to be flipped upside-down, and I will probably lose everything that is important to me. My parents are going through a divorce, and being in my mid-twenties, this should not be such an issue for me, but we own a small holding, with my sister’s stables on, that I and my dad help to run. This was purchased for my sister, by my father many years ago, when he and my mother were still together. Now, today, my father told us that we will lose everything – my mother is not just going to take our plot, but the stables, my father’s pension and she is also gunning after me and my sister’s trust fund. She never consider herself our mother – she told us so, between violent outburst - and only married my father, after her first devoiced husband died and could no longer pay for her lifestyle.
The law in SA is such that the woman in the marriage gets everything in a divorce, regardless of how terrible a wife or how abusive a mother she was. So now, I, who has hardly an income due to the lack of work, will lose the house I live in, my pets and any money that my father would have left for me. My sister will lose her business, and my father will lose his pension. And all to a mother who was an abusive, violent, bio-polar drunk, who never worked a day in her life and has been cruising on other peoples’ money all her life, and she will come out of this rich – very rich and we will be left to pick ourselves out of the dust, if that’s even possible.
I will probably not be able to spend time on DA much anymore until this terrible mess is over. I cannot describe the horrors this woman has inflicted on everything around her, people and animals! Which is why my father separated from her; as he could not take her sadistic cruelty any longer. We have been fighting against her for 3 years, so one has to wonder, if such a terrible person can come out of life getting everything she wants, by destroying other peoples’ lives – then what’s the point of trying to be a good person?
I am sorry for my rant, but I am at a lose at how to survive this intacked
