Taylor saying "try it" is fair but honestly, Susan has a point too about it being hard to believe. I get where she's coming from, because a bad day at work or a mess wouldn't do that. But some things aren't normal problems. When my dad died, I cried for whole days, not just hours. It's not about traffic, it's about a pain so deep it just keeps coming out. So I guess they're both right in a way, but Taylor's not wrong that you can't know how it feels until you've been there.
Honestly, what even happens that makes someone cry for a whole six hours straight? Like, I've had some truly bad days, stuck in traffic forever or spilling coffee all over my work, but that's maybe a few tears of frustration. Crying for six full hours just seems like a lot for any normal problem. It's hard to believe it's really that serious.
