I feel your pain. Remember, a lot of these places tell you up front that they only respond if they want to publish your story. They get thousands of submissions and just don’t have the manpower to respond to every single one.
Don’t let it make you feel cheap. This is what happens in our line of work. Write because you love writing. Believe that you WILL be published. Expect it. Visualize what it will feel like to receive that yes. That’s what I’m doing. Hang in there!
