It’s always nerve racking when you’re trying something new because you’re hopeful for a positive outcome. I think writing it and completing it was the first step. But once you publish it, you’ll realize, hey I actually did it and I’m proud of myself.
I think after I finally clicked that publish button, I was worried about people reading it and liking it 
so I’d say don’t feel nervous and go for it.
And once you publish it, let me know and I’ll give it a read and some feedback
