geekgirl...
You have described my existence to a tee. It is VERY difficult for me to get motivated to do just about anything. I exist day to day. Am very unproductive at work, have let myself go, bills are unpaid until I absolutely have to pay them. It is a vicious cycle that I just can't seem to break.
Sounds like your depression is still more active than you may think. Like a low grade fever... just hanging on to you... not really making you feel extremely ill but impacting you nonetheless.
