Help escape from dangerous home

Hi, my name is Kourtney. I've recently moved back to Pittsburgh, Pa from California with my fiance to help care for my ailing mother. But we ran into a problem. She has severe mental conditions that doctors will not help her with. Over the last two weeks that Ive been back I have been scared for my life. She's volatile and dangerous. She has tried to hurt the family cat multiple times. We have spent all of what we had trying to help her. My entire life I have done nothing but help my mother as best as i can. At the end of the month we will be on the street. I now realize that Ive hit the limit and cannot help any longer in fear of my own life being jeapordized. So, now I am asking for help. My fiance and I need a bit of money to move out of this house. We are terrified for our lives and have no where to go. With your donations we could put a downpayment on a small apartment. That's all I am asking for. Once we get out, my own health may right itself and I could be able to find the right facility for my mother to get the help she needs without my own being threatened. Please, I am scared... I need the help. This is all I'm asking for is a bit of help that I so desperately need.
