How come when we're sad we cry?

Answer 1

Crying or weeping (psychic tears): The third category, generally referred to as crying or weeping, is increased lacrimation due to strong emotional stress, suffering or physical pain. This practice is not restricted to negative emotions; many people 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; emotional tears contain more of the protein-based hormones prolactin, adrenocorticotropic hormone, and leucine enkephalin (a natural painkiller) than basal or reflex tears. The limbic system in the brain is involved in production of basic emotional drives, such as anger, fear, etc. The limbic system, specifically the hypothalamus, also has a degree of control over the autonomic system.

like it doesn't matter who sees you and no matter what you think about, whatever is making you sad comes back to mind. it feels like life should stop for the time when you are at your weakest point. No matter how you try, your heart feels like it is going to give way and burst or just explode on that moment and all you can do is be where you are and let the river of tears stream from your eyes, if they are still there from the amount of water and pain coming from them. never should anyone have to experience this kind of pain, but at some point everyone does, so maybe you know or you will. NOT that i wish this upon you. if you wanted the technical version, well, you typed the question in the wrong way.
