I feel your pain. While my mom isn’t 99 yet. She’s got issues that need daily attending to. It’s not the same as your situation, but I am completely alone doing it. I’m busy as fuck working and my phone won’t stop ringing with more work. My daughter still feels like shit, she’s constantly fighting with her mom. By the end of the day I can barely walk, but still have all my shit plus mom’s shit to do. I need a coma.
