In mid-July 2011, my company told me I could no longer work internally and had to find work supporting a client (what I was originally hired to do). They told me I had 30 days or they would put me at an office in DC, 90 minutes one way without traffic. My husband already has a 2 hour one way commute, so we can't both do it.
Honestly, unemployment never crossed my mind. I spent every waking minute looking for a new job, and had one within two weeks, the same one I have now still.
So I think your focus needs to be on finding a new job, or sucking up the commute for some time. I don't think unemployment should even be an option on the table for you, honestly. The commute isn't un-doable, just a huge pain in the rear. Here in the DC area, people do a lot worse than that though and would never consider stopping to file for unemployment.
I am sorry if that sounds harsh, I do not mean it too. I know this stress all too well, both my husband and I work in the contracts world and we face this kind of stress almost yearly. But we always focus on getting a new job....unemployment won't bring in nearly what you make now (I'm assuming here). I don't know what line of work you are in or what your network is, but I'd spend much more time job hunting and use filing for unemployment (once you are officially let go) as a last resort.
