And I'm kinda freaking out a bit because that's been my lifeline throughout my weight loss, especially when it comes to weighing things like meat because I don't trust myself with eyeballing. I can't get another one until Friday when I get paid. Ugh! What would y'all do in this situation?

That blows. When I'm in a pinch I use http://www.caloriegallery.com. It helps when I need to eyeball things on the fly. Hopefully someone else will pitch in with some helpful advice.
