Ever get that empty feeling when you finished something you really liked?

[Doobie_wop]

It's this weird hollow feeling that you get in your chest and it comes up nearly every time I think about that specific thing.

I felt it when I finished the Harry Potter books.

I felt it when I finished Oblivion and Yakuza 3.

I felt it when I finished Beck: Mongolian Chop Squad, Neon Genesis Evangelion, Cowboy Bebop, Gantz (anime) and Full Metal Alchemist.

I thoroughly enjoyed all these things and I invested lots of time into all of them and every time I think about them I get that weird feeling and It's pretty annoying. Besides the games, they all leave so many questions unanswered, they leave me wanting a next instalment and they actually ruin other books, animes and games, because in my eyes they will always be superior. 

Does anyone else get that hollow feeling?
