Off the Wagon

I've fallen off the weight loss wagon. Since I have no scale and haven't been to the gym in a few weeks I have no idea what my weight is, but I know it isn't pretty. I try to focus on the goals I have stuck with, drinking more water, walking more, eating organically, but I can't help but beat myself up at least a little for my lack of consistency with the whole process. I suppose there's nothing left to do, but pick myself up, start again with the healthier habits and try again, but I can't help but feel disappointed in myself. I want to get to a place where I look in the mirror and feel pretty. Why is that so darn hard?
