Lost in Space

Hey guys,
Sorry I haven't posted in a couple days. I've been lost in a void. I guess the only thing that I had to write about is the fact that I can't seem to write anything else. Writer's block sucks especially after having a great session with a friend of mine editing the next installment of Sandriel's Lament. We talked about character development, plot, setting and how it connects to the main story. I took some great notes and then when I sat down to revise it....NOTHING. I can't seem to get out of my own way. Have you guys ever had a situation like this? This is my first book and after speaking to a couple writers at NY Comic Con the consensus is that the first is always the hardest. I feel like this book will never be completed and sometime I feel like I am driving my friends crazy with story ideas. Hopefully this will pass soon. I really want to share this story with everyone. Any ideas on how to chip through this writer's block?
