Sadness can be legitimately problematic, absolutely. If your sadness comes from seemingly no place or even an obvious place but keeps you from participating in life or enjoying anything and refuses to abate no matter how long you go on letting it express itself, you of course can’t keep living like that. But culturally, we aren’t allowed to be sad even for a little while. Even when it’s perfectly sensible. Even when, sometimes, we need it.
