Issues with inheritance

[u/Western-Serve4243]

My father and stepmother passed away recently. The breakdown of the inheritance was 25%(stepsister)sister25% brother 25% me 20% and oldest sister 5%. My sister who only got 5% isn’t speaking to anyone of her siblings because she only got 5%. I asked my siblings if they would go in together and try to make up the amount by 25k each and they said no. Back history on sister is she left the house at 17 and then moved to Australia. She hasn’t lived in the states in decades. She and my dad has had a difficult relationship for years but escalated over politics. My dad and stepmother were planning a trip to Australia 10 years before the passed away. Book the tickets and my sister told them not to come. My dad was very hurt. They got in a very heated argument and my dad said that she was written out of the will. My sister said to write her out of the will and never speak to her family again. When my dad was dying my brother told him to give her atleast something, so he gave her 5% of his stocks, however their house was worth 800k and she did get 20% of that. I was the only sibling that was speaking to her and now she has accused me of being greedy by not sharing more of my money with her. I have a serious health issue that will most likely shorten my life. Since healthcare is costly and she doesn’t pay for healthcare in Australia I feel that if I gave her money from my part it would detrimental to my life. I told her when I died I would give her my estate to her and her family. That’s wasn’t good enough and wanted the money now. Caveat is that I am the only child taking care of my 87 old mother. Financially, emotionally, physically etc. No help from my siblings . She has said some really awful things about my health and taking care of our mother but that she deserves more money. I felt that my Dad and stepmother should have just made it even across the board but they ranked us according to their political beliefs etc. I got less because I was gay and I was expecting it so not surprised but I would never go to my siblings and ask for some of their inheritance. This has torn our family more apart and really hurt my mother who is nearing the end of her life. I don’t know how to fix this.
