Sarah, I am sorry that you are in a funk.

We all get that way sometimes. I sometimes play the head game myself, "Why am I not losing as fast as others?" Pat on yourself on the back that you have lost 12 lbs!

That is an accomplishment in itself, and you have made a concious effort to change your lifestyle. I know for me, changing a lifetime a bad habits takes some doing, and there are times when I question what I am doing because it is so hard. But then I realize that it will take time to lose the weight, just like it took time to gain the weight. Sometimes, for me, when I am in funk and not losing the way I would like to see, I actually go back to the basics. I am on a set program, so I re read the material. I make a concious effort to journal, and or course check in a 3FC. Sometimes, I actually take a complete break and just try and maintain. When I change my routine I find I get a pleasant surprise on the next weigh in.

By mixing it up, I think it helps as well. Remember, it is just a number, the fact that you are working on being more healthy is fantastic!
