Frustration

I am a little frustrated, first I have not excersised and I feel like I am slowing down again. I have been 79lbs down since last friday. I need to lose this last pound. My goal is 33 more pounds . That will put me at 140 and I think that is a great weight. I am right now a size 14 and I do feel like my pants are getting a little big, so that is a good thing. But i need to excersise !!
