This is a tough time for you, man. There's not a lot that's in your favor.
You know what's best, and that's what you're going for. I'll only add that you should take care of yourself first. Many obviously rely on you, and they'll need you at 100% for optimal support.
My condolences for your losses. And it's good news that your brother is healthy now.
It'll get easier. Take time to breathe and stay resilient, man.
