I'm looking through the pdf file of the spousal visa from the UKBA. I'm not filling anything out yet, but I have a real quick question. It feels like I'm asking a lot of dumb ones, but I don't want to check the wrong thing and make a dumb mistake

On Question 5.2, it asks you to check a box indicating your employment status (i.e. full time, part time, unemployed, self employed, etc.). At the moment I'm unemployed--the agency I was working for last year has me on their books as looking for work, but they're very short of it at the moment. I don't really see it changing much anytime soon, our work was reliant on work that companies contract out to our agency, and it's been few and far between.
I'm lucky enough to have a mom that is helping me out though. She pays the bills (they're in her name anyway) and I just help out around the house. I've always lived with her (I'm only 23, not young, but not too old either), and when I'm working I help out with the bills but right now I'm not.
This is the question: assuming I'm still unemployed when I file my application, which box do I check? There's unemployed, and then a box for being supported by a spouse/partner/family member, and I'm not sure which I fall into. I don't get any money from my mom (i.e. she doesn't give me a check or cash), she just pays the bills herself, but I am staying here with her. I think I would just check unemployed since she's not technically giving me money to support myself with, but I wanted to double check with people who have filled this stuff out before. It's a dumb question, but I'm not sure, and I wanted to check so I'm not having to figure this stuff out at the last minute
