I've written about 35k on my first novel attempt, but now I feel like I'm stuck. The plot's getting confused and my writing quality has seemed to gone downhill since I started. I stare in front of a blank screen and haven't written in weeks. I just feel like I can't write well at all and my story's a mess. But I've been working on this a lot and don't want to throw it all in the trash and give up on this story. What should I do? Start writing something else? Give up? Keep going with this story? Any advice would be greatly appreciated. Thanks.
