What is wrong with Hamlet?

How can people get ready to the death of someone? You cannot get ready.
Hamlet has an exystential problem: "What is the sense of may life ?" Hamlet finds himself in the middle of nowere, he is not able to find the way, he is stuk, he cannot act.
Why is Hamlet's mother worried? Why does she not accept Hamlet is suffering? Why does Hamlet not acceplt the way Claudius addressess him? Why ih he suspicious of everyone? Is he insane or is he pretending of being insane? Should he take revenge? He does not know what to do. Hamlet is filed with imagery of decay and death, corruption and disonesty, reality versus unreality. Problems: marriage (mother-uncle), power, take revenge.
