First, I'm happy you got out of that job. It sucks you got terminated, but a shitty job is a shitty job. I know how you feel with a job that is slowly taking your soul (I worked at Fry's Electronics for several years), so I can attest to your relief at being terminated.
The great thing here is now you have a completely free schedule to do what YOU want to do. Take advantage of that for a few days. It will do you a world of good. Just a few, though. Because you'll need to update your résumé and get down to job hunt after.
I'd also take advantage of your health benefits before those expire or are revoked, too. Get new contacts/glasses, teeth whitening, full body scans, the works. There's nothing sweeter than bilking a few extra dollars out of the place you hated while you're no longer there.
I wish you luck in the future with a new endeavor. If you're around, drinks will be on me.
