*hugs* You can do it! Go even if you are feeling lazy about it, afterwards you will feel proud of yourself for doing it anyways. And if you give in to the lazy feeling not only will you likely feel guilty for giving in, its also that much easier to give in to it the next time, and the time after that etc.
Just think of those 7 lbs, you are so close to your mini goal, let that energize you through it!
