Being honest about the lack of exercise

Pacing around the house is a poor example for exercise.  I know that I am putting myself down, but that is what I did today.  I had a rough week with obsessive thoughts and sleep disturbances.  At least I had a good cry.  It is time for me to exercise.  I have been sidetracked for a while, but I cannot use it as an excuse.  I don't want to remain lazy and unmotivated.  I want to go out there and exercise.  It would benefit me greatly.
