Future cut short

My sister had her future planned with her partner in life. They moved in together got there families together. She became step mommy to his littles and he became the father figure to her kids. He tragically passed after severe pancreatitis caused his organs to fail suddenly. She has little to no fight left in her and I just want to make sure she is concentrating on healing and not feeling like there is nothing left. Absolutely anything would help she would never actually ask for help but I know they will need it.
