Congrats on your first workout at Curves! Yes, you really can love exercise.
How about this for a suggestion? Choose one scale and weigh on it once a week at the same time every week. You know, I don't even let the doctor weigh me. I tell them what I last weighed at my Weight Watcher meeting, and if they want to put that down fine, but I'm not weighing on their scale fully clothed after eating several meals and downing a bunch of water. I know what happens to my psyche when I see that higher number.
