From Umbridge, his disastrous relationship with Cho Chang, the failed rescue mission and subsequent death of his godfather Sirius Black, to learning about Tom’s Horcruxes, the murder of Dumbledore, Harry, Ron and Hermione’s mad search for the Horcruxes to the Massacre. Then, it was the last eight years Harry spent alone, hunting down Death Eaters and doing nothing but killing until that final battle.
