Because we get so filled up with emotions that it spills out of our eyes!

Because you are experiencing a momentary/temporary feeling that everything is going wrong. Don't worry however, this feeling never lasts too long. It is in human nature to feel depressed, but not in human nature to feel depressed for very long.

Most mammals will produce tears in response to extreme pain or other stimuli, but crying as an emotional reaction is considered by many to be a uniquely human phenomenon, possibly due to humans' advanced self-awareness. Some studies suggest that elephants and gorillas may cry as well.

Because you are really angry. Once you develope your anger and mature it you will be happier with yourself and have a personality to recon with. That way you can be sad when your sad and happy when your happy without being unsure.

Crying or weeping: Is increased lacrimation due to strong emotional stress or pain. This practice is not restricted to negative emotions; many people have been known to cry when extremely happy. In humans, emotional tears can be accompanied by reddening of the face and sobbing — cough-like, convulsive breathing, sometimes involving spasms of the whole upper body. Tears brought about by emotions have a different chemical make up than those for lubrication. \n\n\nSome claim that humour cannot or should not be explained. Author E. B. White once said that "Humor can be dissected as a frog can, but the thing dies in the process and the innards are discouraging to any but the pure scientific mind." However, attempts to do just that have been made, as follow.

On the Origin of Crying and Tears\n\n \n\nHuman Ethology Newsletter, Vol. 5 Issue 10, june 1989, p. 5-6\n\n \nSummary\n\nCrying and tears may be favored by natural selection because they bring about helping behaviour by the spectator. This helping behaviour is explained by the assumption that crying and tears “imitate” some of the perceivable characteristics of a baby that has just been born (e.g., wet face, facial expressions, respiratory sounds). If human parents and people in general are “programmed” by evolution to feel the need to help and protect when they see (and hear) newborns, then when nonneonates are in need, the appearance and the behavior that together show resemblance to the neonate may have survival value at some essential points during phylogeny and, thus, may spread in the human species.\n\nIn ontogeny, the fact that the shedding of tears usually occurs for the first time not until weeks or months after birth is not an argument against this view but, rather, supports it.\n\n \n\nSome Theories Regarding the Function of Emotional Tears.\n\nIn The Expression of Emotions in Man and Animals, Charles Darwin listed three reasons for the secretion of tears: “The primary function of the secretion of tears, with some mucus, is to lubricate the surface of the eye, and a secondary one, as some believe, is to keep the nostrils damp, so that the inhaled air may be moist, and likewise to favour the power of smelling. But another, and at least equally important function of tears is to wash out particles of dust or other minute objects which may get into the eyes” (Darwin, 1872: 169). In Darwin’s view, the excretion of emotional tears was related to the first function.\n\nIn more recent years, A. Montagu (1959) offered another explanation of emotional tears: The intake and expulsion of air that occurs in sobbing would cause the sensitive mucous membranes of the nasopharynx to dry out quickly if tears did not keep them moist, and as a result, the risk of infection would increase. This explanation was criticized by W.H. Frey (1982:9) who wrote: “Humans do not excrete tears while running or performing other exercise where breathing is increased.” He hypothesized that, like urinating, defecating, and exhaling, emotional tearing may be involved in the removing of waste products or toxic substances from the body. Perhaps people feel better after crying because as they shed tears, they also shed, in those tears, chemicals that build up during emotional stress.\n\nThese explanations are essentially physiological, and Darwin made explicit that he assumed no other, more fundamental reason for weeping. He wrote: “…we must look at weeping as an incidental result, as purposeless as the secretion of tears from a blow outside the eye, or as a sneeze from the retina being affected by a bright light, …” (Darwin, 1872: 176-177). In his view, the sole effect of weeping or crying is to give relief to individuals who are experiencing the agony of pain.\n\nIn contrast to Darwin’s point of view, the explanation that follows directly links crying and the secretion of tears to evolutionary theory. Crying and the emotional secretion of tears are considered here to be messages that contain a request for help, and humans have the ability to cry and to shed tears because these messages have proven to be effective.\n\n \n\nAn Evolutionary Explanation of Crying and Tears.\n\nThis explanation is based on three assumptions.\n\nA.       In many species of animals, the stimuli emitted by newborns bring about parental care. In fact, the newborns of many species require parental care. Because a newborn has little else to offer than its own appearance and behaviour, it is logical that it is exactly these factors that elicit the parental care. Parents who do not react in the appropriate way to the appearance and behaviour of newborns reduce the fitness of their offspring and, therefore, the likelihood of the occurrence of behaviour rese

Because men are supposed to be the emotionally strong and balanced ones. And crying is a sign of weakness...or so people think. I do not believe that.

First - the words are copacetic (not "copastedic") and themselves (not "them selfs").\n\nIn answer to your question - it's just the way some people are.  They're not happy unless they're unhappy. :)  Maybe they don't feel they deserve happiness?  Or they hold on to negative feelings, because they wouldn't know what to do without them?

It's all psychological and "anatomical (?):" When you hear something that's emotionally painful to you, your brain starts to think differently and asks and answers multiple questions at the same time, consciencely or subconsciencely. To some point of this simultaneous complex thinking, it will tell the tear ducts to expel tears for no reason. Also, it will have some kind of pain around your heart (the heart-break feeling).\n\nI don't know exactly why the brain does that, but I think it's merely psychological. All animals do not cry for emotional or physical pain (salt-water crocodiles "cry" to expel salt). My hypothesis would be that sometime millenias ago, crying was a sign of sadness in some way, then, as evolution takes place, it just becomes embedded in our mind that the instinct when we're in pain, we tend to cry. But that's just my hypothesis and to my extent of my knowledge.\n\nPS Penguins!!!

that is a very good question....I guess I would have to say cause some people are never satisfied with anything or just aren't happy unless they have something to complain about on a daily basis to make them happy...or that they wont be happy until people around them are miserable just like they are

i think weeping sometimes can really externalize that held within. and feels better. not sure about full-on crying, its kinda rough, blocks my nose, eyes all puffy, b/p and hr elevate, i think all that drama sometimes only feeds negativity.\n\nawww schneb :-)

Tears can be an expression of Joy....One of lifes most wonderful joys is falling in love and having your love wanting to spend the rest of their life with you. P.S.- Women aren't the only ones who cry, I cried when she said yes.

Some people use it like I used to. It puts the shock of life back into You. Sounds weird but no other way of putting it. Sadness and anger I vented on  fighting and loving the feeling of hurting another. Getting hurt only enraged me more scarring my loved ones away. The night my wife said she was to leave with my infant daughter, I broke down and cried for the first in nearly 15 years. It felt like a baptism. The water and blood that comes from inside you will change You always. It isn't crazy nor a ploy to  get attention . Everybody changes or is humbled at different times in life. That's how we are unique.

Two reasons: 1) Stress causing chemicals exit your body via tears so you cry to lower your stress level.  2) Its a visual clue to others that you need help.  Studies have shown women cry more around men who don't notice less conspicuous signs of sadness and stress in their mates.
