I appreciate where you're coming from, especially since both songs are so similar.
I don't understand the notion that your song is somehow special and unique. It's not something that is unlike anything ever heard before. You didn't create it in a vacuum and I'm sure you didn't pay anyone royalties for the inspiration you had when you created it.
It's music - we need to get over this 21st century notion that we somehow own the notes/arrangement/lyrics and can ignore the thousands of years of history of musical creation, and start laying land claims now and insist everyone owes us when they create something similar.
You are talented and creative, but you are not unique, and your song is just like many before it. Take it as a compliment if you feel they are "copying" you and use your talents to create something "new". You'll feel much better about yourself.
