Is it illegal to put odorants in buildings to cause severe depression and paranoia?

Could it be that someone accidentally spilled or dropped their belongings to produce this smell?

Or the gas released by sterilization and disinfection in the building?

Is this often the case?

You can report the situation to the property, community managers, neighborhood committees and even the police!

See what they said?

Regarding the mental and psychological problems you mentioned, I suggest you:

Broaden one's horizons, broaden one's horizons, be open-minded,

Don't entertain foolish ideas, subjectively assume some problems, and make unfounded reasoning and judgments.

Don't make too extreme and exaggerated assumptions and guesses.

Can you talk to your relatives, friends and neighbors about the smell and listen to your opinions?

Could it be that you are too sensitive or misunderstood something?

Usually do more outdoor activities, exercise and adjust your physical and mental state.

When you find time, it is also recommended to consult a psychologist.
