I am very aware of my mood states but I have not always been. I could always tell the depression was there because I would start thinking people were saying horrible things about me behind my back...Christ now I see the paranoia...just great.

Anyway I suggest charting your mood every day in terms of numbers, not mood. I use a 1-10 scale. 1 is suicidal and/or active self harm. 10 is I believe I'm magical. Normal for me is 6. Five is just meh.

It might help you detect a pattern and you wouldn't have to label a mood state until afterward. Might help you be more insightful.
