One way of understanding mood is to look at these factors:
Consistency:

Are you experiencing the same types of feelings and thinking in a similar way over a period of time?
Predictability:

Can you and others predict how you will respond to external circumstances?
Appropriateness of the Response:

Is the response to the situation an appropriate response based on the degree of

threat, urgency, or importance of the situation? One way to understand appropriateness is to ask yourself would a person you

respect, value, and trust respond the same way? Or would someone who really cares about you and believes in you want you to

respond that way? Maybe, would you choose to be treated this way?
Impulsivity:

How much thinking takes place before a response?
When assessing mood, notice things such as the time of day, how you slept, if you are hungry or tired, the temperature and weather. These all affect mood.
To better understand your present mood take these factors and scale them between 1 - 10
