Even though finding a traditional publisher that wants your work is incredibly validating, there's nothing wrong with self-publishing. Just get an editor that believes in your story and wants to help you make it the best it can be. Revise it a couple of times and put it into the world. As mentioned before, Goodreads is an excellent promotional tool. Do giveaways to get your book out into the world and generate some early reviews. And there's nothing wrong with family and friends writing reviews - as long as they've actually read the book and their thoughts are genuine!
