Feel so empty after finishing the game

I just got the good ending and when Sayori said to "come visit us sometime", I just felt so sad since I knew I couldn't. I grew to love these characters and in just a few hours the story is over. The side stories were nice, but not nearly enough. Maybe it's because I've felt quite lonely recently and seeing stories of friendship kinda fills a void. What do you guys recommend doing after playing so you don't feel so depressed/obsessed over DDLC? Also do you believe we'll ever get a sequel or spinoff?
