Short story: what do I do next??

So, I have this piece that I wrote a couple years ago for a college class. The story takes a look at the afterlife and follows the journey of a new sarcastically comical spirit with unfinished business. It started as flash fiction, but due to my inability to control myself ended up being a 10,000+ word beast… and now I have no idea what to do with it. I want to get this piece out into the world, but I don’t know how. Please help?
