Is it normal that i feel empty/abandoned after i finish my favorite show?

So I recently finished watching all three seasons of Highschool DxD, an anime and my all time favorite show, and I really want to find out more about what happens because I feel like each episode is left on a massive cliffhanger even though the story does a good job closing it up for the season finale. But I can't help that I feel like I've been abandoned and I feel really empty for a while and it takes forever for me to get over it. This has happened to me twice with this show and the first time was so bad that after I finished the first season, I didn't watch the show for two years later, which to my pleasant surprise there are two more seasons! And now that I've finished the show again, I feel lost again. is it normal That I feel this way? Alone and lost? I've tried starting new shows similar to it, but I think that makes it worse.
