after much research (mainly on google), this is an article ifound in regards to why do people cry, and i’ll quote:

“Three types of tears are generated by the human eye. Basal tears protect the eye and keep it moist. Reflex tears flush out the eye when it becomes irritated. And emotional tears flow in response to sadness, distress, or physical pain.
Studies have shown that emotional tears contain more manganese, an element that affects temperament, and more prolactin, a hormone that regulates milk production. Sobbing out manganese and prolactin is thought to relieve tension by balancing the body’s stress levels and eliminating build ups of the chemicals, making the crier feel better.
But this minor physiological benefit aside, the most likely reason we produce emotional tears is because it’s a means of communication. Before babies can speak, they can cry. The only way for infants to express frustration, pain, fear, or need is to cry. Adults may use crying to bond with other humans. Expressing sadness can prompt comfort and support from peers. Different languages can provide barriers to spoken communication, but emotions are universal. There are also culturally acceptable reasons for crying that bring people together, such as at funerals or weddings.
Though there is a significant debate over whether animals have emotions and can express them, some animals do appear to cry for emotional reasons. Elephants seem to grieve when a family member dies and will guard the body and travel long distances to view it. Elephant experts at the London Zoo once told Charles Darwin that the animals do indeed mourn. Chimpanzees also appear to cry, but some scientists still insist that the tears released by these animals are strictly for cleaning the eye.
Whether or not animals shed tears for emotional reasons has yet to be scientifically proven. Humans, however, can and do dissolve into tears for any number of reasons. Cleansing the eye, relieving stress, conveying pain, communication, and societal assimilation can all lead to an empty tissue box.”

THAT IS WHY.
ithank God for such mechanism.
and for tissue boxes.
