When I was younger I was told that emotions are weak. That displaying emotions outwardly showed innate weakness and so everytime an emotion was shwn a punishment had to be issues in order to "toughen" up the person.
These punishments varied from being locked outside for crying, to having water poured over your head for complaining about something. Time would be spent sitting in the corner as punishment, or being told to "go away" and "never come back" because you were "weak, pathetic and an embarasment on everyone".
But emotions are part of being human. They are NOT a sign of weakness, they are NOT pathetic, and we are not bad for feeling them nor expressing them.
