I call crying a "retro-appetite"; something inside that must come out, similar to anger, laughter, creativity, etc.. You may feel that the improvement in your mood has a time lag of between 50 and 180 minutes. Some folk only notice the improvements brought on by crying over a day or so after they've cried.
Sometimes, you may notice improvements in ordinarily unconnected things such as your ability to think clearly, concentrate more closely, write stories or poetry, draw, sketch, paint, and so on.
It's also important for tranquilliser takers (for example) to remember that any strong dose of a tranquilliser will cause "odd" thinking and definitely causes a weepy breed of depression that comes and goes in the guise of 'cyclothymia', or mood-swing disorder. Even some painkillers can do this, also.
Crying is always better out than in.
For those who experience difficulty in starting up their crying, well...you may be surprised to know that, often, you can very easily move from laughter to crying. The transition is extremely fast, once you master this. If you are, in some way, able to summon laughter, you will probably find that you can slide right into healthy crying from that...it's worth a try.
I use movies to help me to cry and some of those movie scenes are very capable of reducing me to a blubbering wreck, every time I watch them.
In the face of maverick unhappiness, it pays to box clever and stay clever!
