When I was 20 years old, a guy once said one of the wisest things I've ever heard:
"Harrison, every man's got the dog in him. Ya gotta know when to let him run loose and be a wild wolf, and when to let him be a playful puppy."
Society and religion want to kill off, if not spay, the dog. They use the pressions, which my friends Alf and Zed had once explained.
All of those often lead to depression.
As for the balance between the wild wolf and the playful puppy: every man must figure that out for himself.
