For me crying is a natural response human have to a range of emotions, including sadness, grief, joy, and frustration. When we cry, we open ourselves up. It unlocks the unspoken problems that are blocking us from effectively communicating, by removing the obstacle of attempting to lock down and hide our emotional response. And also when we cry we remove tension. We get stressed, and it builds up, and it can feel like a huge wave of difficult emotion is cresting inside us. It's incredibly hard, and that's okay. Crying takes that out of the equation. However, sometimes frequent crying can be a sign of depression.
