Seriously guys, what's the point?

I feel like people don't like my books anymore or they've just lost interest, I've been trying hard to entertain you guys but no matter what I do, I feel like I'm making you guys loose interest, I've tried to create loads of new books with good covers but that doesn't really do anything.

I've really noticed it on my Adoption Center book because when I first started that book, loads and loads of people came and adopted from it but now they're only like 5 people.

I'm trying my best guys but it looks like it's not enough, I love writing things for you but people just don't seem interested anymore....
