I can certainly relate to some of it. Most of the time mood and energy changes come at the same time however there are definitely times when the energy comes first(exercise or cleaning all night) and then my mood becomes elevated with loss of productivity(main focus on pleasure such as high libido how good exercise and dancing feel, mindless activities focused on how beautiful everything is) and only after that do my thought start racing etc. They then turn bad and only extreme exercise, research and writing along with alcohol help otherwise I am physically and mentally uncomfortable. Medication could probably help as well but I have never turned to that up to this point, I am more likely to go off meds at that point.

Depression I have always described as extreme exhaustion. I would often be so tired that I could physically not deal with things. I would lie down on the floor wherever I was in my house and not be able to get up for hours or fall asleep before my kids bedtime which was dangerous as they were very young then. This was before medication. Some of the time I would have the low mood as well and sometimes mood would be normal other than being upset about the exhaustion. I know this was not a physical problem as I would always go to the dr and get many tests done which would come back normal. In fact when I was on seroquel daily I told my Pdoc it was exactly like being depressed just due to the exhaustion which is definitely my most consistent symptom.

I dont know that I have ever had low energy with racing thoughts or creativity though.
