I cannot decide whether to remove my mother from life support

Dear Delyara, My mother suffered a severe brain injury. The doctors say meaningful recovery is extremely unlikely, but they cannot say impossible. My brother wants treatment continued. My sister believes Mother would not want to live this way. I am the legal decision-maker because Mother named me years ago when the choice felt theoretical. Every person now interprets her past words differently. She once said she never wanted machines. She also once said every extra day with family was worth fighting for. I sit beside her bed listening to the ventilator and wonder which sentence should govern the end of her life. Nurses ask whether we have reached a decision. Relatives call with stories about miraculous recoveries. The doctor uses percentages. My siblings use memory. I use neither well anymore. When I hold Mother’s hand, her fingers sometimes move. The neurologist says it may be reflex. My brother calls it recognition. I do not know whether hope is seeing life where it remains or refusing to see that it has already left.
