Worn down

Work this week has worn me down.  Too much of a lot of things.  None of them on their own would have been any big deal, but there were just too many of them for me to manage.  It scares me when I feel so overwhelmed.  A bad week and the slide to depression feel the same.  Rationally I know that bad weeks are normal and that they will just happen.  Emotionally this is hard to internalize.
