I wouldn't sell my gear if I was the one sick, but I'd sell it all in a heartbeat for my wife and son. There will always be gear, but there's only one of an individual.
Prayer away, bro. I know where you're at right now. I lost my mom a little over a year ago to cancer. Though I miss her alot, It is comforting to know that she's in a better place now. Stay strong, and all the best.
