Book Reports / King Lear; Lear divides his kingdom - problems with my points [6]

In my essay, I'm proving that Lear must suffer to become a wise man, but, I'm having a few problems.

As my first point, I talked about the first scene were Lear divides his kingdom. I outline the speeches by Goneril and talk about how Cordelia's was the true one. I want to close the point but, I'm not sure how because Lear is not suffering in this scene. Help me, please!
