How does the reluctance of the characters to discuss issues result in negative repercussions? with citation Hamlet, Ophelia, and Leartes

I suppose a big court therapy session might have changed the outcome of this tragedy. If only they would just talk to each other! But alas, Shakespearean narratives are often built on false assumption, pride, and just being clueless. Did Gertrude actually think Claudius was a good guy? The relative emotional isolation of all the main characters are what makes the story the poetic train wreck that it is. Laertes is pretty naive, Hamlet is depressed and even suicidal, Claudius thinks he's going to Hell, Ophelia feels trapped.....It is these levels of isolation and lack of meaningful discourse that provide the inertia for the final train wreck at the end of the play.
