Mood is a powerful word. It actually comes from older words that mean spirit, mind, to strive, be energetic, and courage. It is also being referred to as customary behavior or custom. Thus, mood means way more than being happy or being sad. Moods encompass much from what you need in order to live. Spirit, mind, to strive, be energetic, and courage – are all related to moods and your sense of well being.  
Your mood becomes independent from you experiences. This disconnecting experience and mood presents various challenges in your daily life. Sense of self confidence and self identity can also be affected. Symptoms like extreme irritability also affect relationships. Hopelessness and sadness may become too overwhelming. The sense of oneself can actually be lost if you don’t know what you need to expect from your mood.
