This. A lot of people have problems that they're just better at hiding or coping with.

There will always be stories of normal, seemingly happy people who reach a breaking point one day—having a mental break under stress, quitting their job out of the blue, attempting or committing suicide, harming or killing someone, etc. And while folks want to pinpoint something that must have caused this sudden shift in behavior, it's never just that "one thing." It's a compounding burden of ignored warnings and masking. They give the impression of everything being alright, until it is suddenly and dramatically not.

Basically, you never know what battles someone is fighting, which is why it's important to treat everyone with dignity and respect, without just assuming someone must have it easy in life because they look like they have everything figured out. They're just in their tolerance threshold.
