9 and 7

Hamlet finding out that Claudious is the murderer to his father triggers Hamlet's insanity into whole other level.  The news becomes a heavy burden on Hamlet forcing him to act mad where as sometimes he cannot  contain it; the  insanity leads Hamlet to be obsessed with the thought of blood thirsty  revenge of Claudious.  Hamlet's indecisiveness of revenge drives to the point of nuts thus him questioning himself non stop and repeating himself for reassurance. 

Hamlet's soliloquy clearly illustrates  that the death of Hamlet's father creates a sharp discomfort in Hamlet. The death of his fathers makes Hamlet emotionally unstable.  Hamlet concealing all his hurt and emotional distraught to himself during his soliloquys is a key reason to what drives him insane because the emotions continue to build and build until he eventually can not control it any longer driving him to make "mad"   choices.  Hamlet's choice of concealing his emotions is the last thing he should do and rather he should express or "vent" his emotions to one of his good friends such as Horatio.
