Welcome!
I suggest finding something new to be excited about, and focus on that more than the scale. When I get into a rut and am putting all of my energies into worrying about the scale it doesn't go down. But if I shift my focus into being really motivated about my plan and not so much the results I relax and soon enough the scale will start to drop again.
For example, how about finding a new workout that you can really get into? A lot of libraries have exercise dvds, and some equipment isn't that expensive at Walmart or Sports Authority (like resistance bands, or a stability ball). Getting something new like equipment, or even just a cheap but cute pair of exercise pants, often makes me excited to workout.
Or you could try to break out of your normal food choices and look for interesting, healthy foods you haven't tried yet and change up your eating patterns a little. (For example, I recently discovered jicama and I'm crazy about it.)
Good luck! I'm sure you'll find lots of great advice from the wonderful members here. =)
