I use to use it in times when I feel that I am in some sort of "a state" of loosing control (fleeting thoughts, problems with concentration, anxiety ...). For me it's the feedback that works when I'm in some sort of crisis. To see how high the rate for depression is helps me to concentrate upon using the cognitive tools that I know deep within that I can master (but in the moment feel I have little control over). It is scary to feel that one loses the control over the situation, so using it when there is too much to carry gives me the feeling of being on the road to control again. When I use it, I also write down how many hours I have slept, if I eat regularly, exercise and more.

To say it in another way: When I start charting, it is not only the charting that helps, but also to take a grip at all the cognitive tools I know works for me. I have written a list of what to do and what not to do to be able to slowly cope again. For me it is like if I grab the tool "charting" a lot of other tools "pups up" automatically.
