That emptiness after finishing a book (series)

I finished the "All Souls Trilogy" by Deborah Harkness (The discovery of witches is the 1st book) recently, and loved it like no other - and I've read a lot of books and series respectively, my decently sized bookshelf is p packed. Anyways... It rlly had some place special in my heart, it was just so good and perfect for me in so many ways - there was never a moment I didn't LOVE reading it.

Many other amazing series I've read in the past left me feeling a sad emptiness after I finished reading (even though they DID have uninteresting or unpleasant parts to read, unlike tDoW). However, now whenever I hear the songs I played while reading the (DoW) series I feel like, really- REALLY sad. It feels like I will never find or experience another read like that. Its rlly doing a number on me guys and I'm not even reading it anymore ┗( T﹏T )┛
