Everyone is struggling, but just as as hamlet did with his inner conflicts you don't have to hold it in or get revenge just as he does and proves throughout shakespeare's play, he wanted justice for his Father just as the king's ghost had demanded because his was driven by anger and resentment for his murder that it caused Hamlet to trust not even the ones that he loved, it was proven that this inner conflict had only not ruined him but everyone around including Hamlet Friends and Family.
In the beginning, Hamlet was still shocked that he’d known about the fact that the king was killed by his Father
and seeing his ghost asking to seek out revenge for Him, and now suddenly Horatio is suddenly a royal King of denmark and is married to gertrude who i believe is ignorant to Hamlet's struggles, Hamlet is crippled by the lost which causes him to seem ‘crazy’ which polonius is convincing the gertrude and horatio that it is because He has fallen deep in love with his daughter: Ophelia, in which he convinces the king and queen to spy on him in which they all conclude that there is something seriously wrong and he must be sent to europe which may may not help Hamlet's sudden ‘craziness’ but they don't seem to understand why he is truly feeling this way and it makes him less trusting with the his family and friends. overtime he grows angry at his motherr, he even accidentally kills polonius as he hides behind the curtains when gertrude might really realize that something could be wrong yet denies his troubles, he says he doesn't regret killing polonius, he no longer loves Ophelia and had expressed his utter most displeasing for her and her presences as he calls her multiple names, gertrude doesn't really understand and is very ignorant to hatio and what he had done to hamlet.
Everyone struggles with multiple conflicts just as hamlet and just like gertrude, many are unaware of the problems and that we all struggle with grief and the love and trust of trust with friends and family as did hamlet did.
