perhaps the cry is about the emotional movement into compassion from sadness. Tears also contain among other things serotonin—hence the release of this calming neurotransmitter.
You asked if people noticed that a good cry can make you feel better. I was just trying to express that for me it does not seem to do that. Sorry if you did not find it helpful.
In my experience, having a good cry is on the top three list of things to do to help you feel better!You should everyone should cry sometimes!It always makes me feel better afterwards, I feel more at peace somehow….
