I'm working on two kind of books right now. A journal about my life and everything that we thought was real, and a story that explains why I'm so messed up. I haven't gotten very far on either...
If you're struggling to get further in your story, maybe you could take a break for a week. Don't pressure yourself into writing if the ideas aren't flowing. Sometimes I think up my best work when I haven't written for a week, then boom! I get about 5000 words in a night. I wish you luck in your future writing endeavours.
