It should get easier for you after your book is published and, as others have said, once you've published additional books, especially if they're part of a series. I remember how hard it was to get started. But if you keep at it, you'll eventually find fans and reviewers who like your work enough to read your future books. I did a Goodreads Giveaway and that worked out very well for me in finding readers who enjoyed the book I was giving away. That's probably due to Goodreads members signing up to receive the type of book they're interested in reading.
