Check out The Five O'Clock Club. They are a career help company (I'm not affiliated with them and right now I'm not a member of their services either.) They just have a really professional approach to helping people. There's a lot of free information on their website including newsletters, resume help, and so on, and they offer meetups in NYC to talk about careers. It sounds like you need a new job -- not a second job. If I were you I would try putting my focus and effort into that.

And since its the Christmas season, have you thought about retail on the weekends? Its not glamorous, but it can help pay the bills and its entirely different than the work you do during the week. Every time I've picked up a retail position, its been fun and I've worked with good people.
$34K is really low for New York. Its hard to make it on that even here in the midwest where housing is inexpensive.
Best of luck!
