No, you don't.
It's painful, shitty, and won't "bring your family together", if anything it might drag it apart. People will either get tired of having to take care of you, or distance themselves from you because they don't want to watch you slowly waste away.
You survive? Congrats! You have mountains of hospital bills, and the trauma of all the painful shit that happened to you.
I've watched people die of cancer. You get tired and sad and ugly, you feel sick all the time. It gets worse and worse until you die, and guess what? Your result, death, is the same as what it would've been if you just did it yourself. Just much less painful for you.
It's not exactly all sunshine and daisies.
