everyone processes grief differently

> You develop a potentially terminal illness?

I mean, I'm probably going to die anyway. At least if you're alone you don't have to worry about the trade off between extreme medical bills and a few more months of life vs leaving family more money

> A partner betrays you?

I don't really plan on marrying so I'd just replace them with someone else

In all of these situations, you can figure out ways to get through them alone
