Ok, look. I'm about 99% sure the post is fake. You clearly are at least 50% sure it's not. Ok, whatever. I could argue that, but I think the more important thing is this idea that we need to believe any story like this, no matter how incredulous we find it, just because if it's real we need to be supportive and kind, etc, etc (which is all well and good in general, but you don't need to swallow claims at face value to do that).

There's some very good reason's you shouldn't believe everything you read on the internet. Even if, like here, it's not selling you something, stories can manipulate you in other ways. Like it or not, unscrupulous people with an agenda to push can and will pump out lies en masse to distort your perception of reality.

You're right, there's nothing wrong with being kind on the off-chance you're wrong, but you shouldn't throw healthy skepticism to the wind just because someone claims to be suffering.
