All writers go through this at some point(I was there for a few days). I had to talk to other writers, read other writers, and get a new focus. Talking to other writers is great because you get their wisdom(and how they were able to get past it). Reading other writers is great when you can’t talk to a writer in person or when you are an introvert/perfectionist who wants to go it alone. Getting a new focus helps because you can change your frame of reference and find new inspiration.
So I changed my view of my story and am looking at smaller chunks. Now I feel excited and actually wrote a lot last night(while plowing through the Lizzie Bennet Diaries). So I have a plan and focus for today. Remember that when you feel like you are in the dark, write something new to get on the path to the sunshine.
