Unfortunately, not all people are happy.
If there is a deeply unhappy person in your circle, then you should help him: give him moral support, entertain him, etc.
But how can one “figure out” such a person?
The problem is that many people are very good at hiding their extreme distress.
However, even the most secretive unhappy person can “give away” himself with specific behavior.
Want to know if a person is happy? Ask them: "What do you dream about?"
The answer was: "Nothing"? That's a bad sign!
Most likely, your interlocutor is not in the best psychological state.
The absence of a dream indicates that a person does not think about the future and does not strive for anything.
If your interlocutor is constantly irritated by trifles, then know that he is either very tired or is rarely happy.
An unhappy person does not consider it necessary to take care of himself, observe all hygiene procedures, get rid of excess weight, see a doctor in time, etc.
He simply does not see the point in all these actions, since he has stopped loving himself.
Such a person needs urgent moral support.
