He was all alone in the world. No one to help him. They were all gone, and Harry was the only one left.
Ginny. His girlfriend and joy in the world. She was one of Voldemort's first victims, or rather Bellatrix's first one. At the Final Battle of Hogwarts, the green light had speeded towards her, and before Harry could shout "Move!" she was slowly falling, embracing death, and taking away Harry's heart.
Hermione. He wasn't sorrier in his life than now. All the times when he could have supported her, when she had helped him countless times with his essays, when she had his Firebolt confiscated, but with good reasons, he didn't say a single Thank you, and now she was gone. He could say a thousand thank yous, but with no success.
Ron. His best mate and his second. One of Voldemort's direct victims. He died to protect Harry, stood in the way of the killing curse, and fell backwards. Voldemort then Banished the body, feeling no need to keep it. When he thought of it now, Ron would have wanted to kill him countless times. He had heard it in the horcrux. He was the least loved among the trio. Harry felt so sorry.
A thousand Sorrys couldn't cover his mistake.
So he stood in the way of the Avada Kedavra Voldemort sent at him, longing to see the ones he loved. He could hear them calling him.
