This is Harry Potter and a fan fiction of what happened right after the wizarding war. No copy writing intended; I only own the story line.
After 48 hours Harry opened his eyes and was confused where he was until he saw Madame Pomfrey in the corner of his eyes. She saw his eyes open and quickly jogged her way over to him.
"Are you okay", Madame Pomfrey cried, "I should probably let you rest"
"I'm fine", he lied, "can I rest for a few minutes… by myself" he added
"Oh. Yeah, sure", she said.
Harry had millions of thoughts drifting in his mind like Where are the Weasleys, what happened to me, how long have I been out, and this is all my fault! He thought of how he can't face the Weasleys after what happened to their son and brother. I have to be alone.. For longer than a few minutes, he thought. Harry tried to stand up, but he couldn't push up for long enough to get his head up. One more try he thought. He pushed as hard as he could and now sat up. He pushed his legs to the side of the bed until they fell to the floor. He used stood up and apparated out and found himself at Grimmauld Place. He quickly searched around - with the help of Kreacher - to find a piece of parchment paper and a quill.
He wrote: Dear Weasleys and Hermione,
I would like to express my apologies for causing the death of your son/brother/friend and many other deaths. I would ask of you for one favor though: to not look for me. I will come back in my own due time and would ask not to be looked for. I just need some time to be a lone. I love each and everyone of you, but I don't deserve a single one of you.
Love,
Harry
He called for Kreacher to go and buy an owl and gave Kreacher 5 galleons. 10 minutes later Kreacher found his way back and gave Harry the owl. This time though, Harry had red, swollen eyes. Harry tied the letter onto the owl and told him to go and deliver the owl to Hermione at Hogwarts. Harry lied back down on the ground sulking in his own tears.
Hermione walked with the rest of the Weasleys to Harry's room, but little did they know: he wasn't there. Hermione walked into the room and Ron last.
Hermione still glaring at Ron, she exclaimed, "Where's Harry!"
Madame Pomfrey runs in saying, "He was there a second ago"
"Oh no… No, not another son" Ms. Weasley cries.
Hermione sees an owl at the window sill and says, "smart owl". She grabs the owl and unties the letter, reading:
Dear Weasleys and Hermione,
I would like to express my apologies for causing the death of your son/brother/friend and many other deaths. I would ask of you for one favor though: to not look for me. I will come back in my own due time and would ask not to be looked for. I just need some time to be a lone. I love each and everyone of you, but I don't deserve a single one of you.
Love,
Harry
"Poor Harry" Ms. Weasley states.
"He deserves it" Ron snarks, "It was his fault after all."
"I don't want to hear another word!" Ginny declares, "Harry has been through enough and now he has the burden of hundreds of deaths! No one deserves that." Ginny starts to shed tears.
