Thanks to everyone who responded to my desperate cry for help. With your support and advice, I'm about 90% certain to make the move to New York City within the next few weeks. Most likely I'll be searching for an internship to get my foot into the "writing" door while paying the bills with another job that doesn't tap into my awesome potential.
If you're not the commenting type but you still have some advice about living and working in NYC, I'd be eternally grateful if you emailed me here.
Thanks again everyone!
