Loving something and being passionate about it, doesn't always mean you are good at it. Fictional writing and professional commercial writing are two separate things. If you are a good writer, there are opportunities for freelance writing gigs (copywriting, technical writing, catalog work, long form, short form, blurb, sales, etc.). It is a competitive space, but a good online portfolio with writing samples and consistent perseverance can lead to more work. If you don't have any commercial experience or samples, proof-reading jobs are a good place start.
