I feel like I'm kinda going through the same thing as you, Sarah, Mare, etc... I dunno if I'd call it a slump, but ever since I finished BMS, I have felt kind of lost, like I don't know where to go next. I have two ideas for novels that I like, but for whatever reason, I can't get going on them. I have a novella that I started a couple years ago, and I can't get much done on that either.
I have two Broken-related projects in the work, and those are what I have been working on lately, and I'm enjoying them, but at the same time, I feel guilty working on them because I feel like I should break away and write something brand new. And I'm not sure why I feel that way. My readers, at least over on my forum, say they'll read anything by me, but the Broken-related stuff is met with the most interest. My one attempt to write something completely different only got one review on AC. So it's not like the majority of my readers are pushing me to go in a different direction and I'm the one resisting. I think it's just pressure I'm putting on myself. So now that it's summer and I have all kinds of free time to write, I told myself to just write whatever the hell I want, whether it's Broken stuff or something different, and I feel like I'm getting back into the habit of writing or at least attempting to write every day. And hopefully, once I get the Broken projects out of my system, I will be more inspired to get into one of my other ideas.
