On the down swing

If depression were a disease (well, a disease caused by a virus or bacteria), then I would have no immunity. Seems like every time I come across someone that's depressed I can usually hang around long enough to help alleviate their depression for a time. Then in only a matter of an hour after I've left them I begin to find myself sinking uncontrollably into the same abyss. Worst part is that my ankle still hurts, I have a headache and probably bad breath.
