Get rid of the scale! Or use it to find trends. Don't use it as the end-all of your journey. You're going to come out of this healthier and happier, stronger and more confident; the weight loss is just a by-product of that.
Use other non-scale determinations of your health. Every month, do a mini fitness test. Set a stop watch for 1 minute and see how many crunches, push ups, squats, lunges, etc you can do. Next month, watch those numbers increase! Measure yourself and check it next month -- bet you drop some inches!
The more you weigh, the faster you'll drop weight. The closer you get to your goal, the harder and longer it's going to take. So don't get discouraged. Depending on how long you've been doing this, you could just be freaking your body out!

And remember, this is a lifestyle. You're going to be doing this FOR LIFE. The weight WILL come off.
