I've been worrying about this for quite a long time.
So, for the past year or so, I've been working hard on a story I'm very passionate about. My biggest concern of them all is copyright issues.
I'm not going to bore you with the details, but I was wondering if there were resources(people or online. Technically, this site is really helpful and would count as a good resource for me online, but I want to go more in-depth) that look over my story, and compare it to an existing work that I think could be too similar, and then provide me with advice, so that I can be 100 or near percent assured. I'm not sure if I'm supposed to be asking an attorney, or even my friend, to deem whether my story is too similar to another.
