Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.

It looks like they only do one mood per day. I would say that if you have significantly different moods in the same day then do what you have done, write it down, look for patterns, and build that into your method.
So if your moods change based on time of day, or experiences during the day, note that as well.
idk the chart seems great but complicated?
