The yo yoing is hard, isn't it? I'm so glad that you are forcing yourself to get out for a walk,,,so sorry you fell...one step forward, two steps backwards. It is amazing how it takes such effort sometimes to get out that door...we always feel better once we do...again, it must be our minds doing us in. As it has been pointed out with depression, the behaviour has to come first, then the motivation...let's remember that! "Fake it 'til you make it"....or "until you become it". I hope tomorrow is a better day for you and me both:).
