Is constant crying positive or negative???

Is constant crying positive or negative???
Some say that crying has positives and others say that it has negatives, but from my point of view, I see that constant and excessive crying is extremely harmful to a person.
If the crying is temporary, it has many benefits, the most important of which are:
Improving the mood: After crying, you will always feel comfortable because the negative energy has already left your body in the form of crying
Improving vision, improving sleep quality, improving digestion and alleviating pain because the body when crying secretes hormones that relieve pain
Tell us your opinion: Is crying more positive or negative?
