I put the word 'Ended' in quotes as for me Harry Potter never really ends.
But really, I've not looked forward to anything as much as I did the next Harry Potter book, or the next Harry Potter movie. The mounting excitement, going online and discussing the Ifs and Whats and then finally reading it/seeing it. If read a few good books, watched some movies but I've never really go into anything as much as I did this. I wish I was creative and write some fanfiction (as i love reading it) or drawing some fan art or joining a wrock band but really it's left a big void in my life! Is there anything out there that can take the place of Harry, Ron and Hermione? Or, am I doomed to live the rest of my life with a piece on me missing?
To sum up. Just how has everyone filled that hole?
⇢ I've gotten involved in other fandoms, although Harry Potter is always on the back of my mind.
More recently, I've been really into The Vampire Diaries, Sherlock, Once Upon a Time, and Doctor Who. I've also been watching a boat load of movies and getting into their fandoms at random moments.
Sadly, I haven't been able to find a book series as captivating as Harry Potter was.
This reminds me -- I need to get more involved on Pottermore, and possibly continue writing some HP fanfiction.
