Too many do hold too much inside. Never speaking it and it does grow and fester. I'm not one that believes there is no cure, just those who won't get the perscription. That he was capable of speaking it IMO is a good thing. Yes, you saw how big and ugly the monster is, but perhaps in showing you the monster lost some of it's strength (if only temporarily).
It is all so very sad. I hope your deeper understanding will lead you to a greater sense of peace.
