Everyone has their own name for a feeling of hopelessness and helplessness.
Depressed mood is considered troublesome if it is intense, severe, and continuous.
Some individuals who suffer from depression also have periods of time when their mood is elevated or irritable. They often describe their mood as fluctuating between highs and lows. When their mood is low, their symptoms are similar to other individuals with depression. However, when their mood is high, they become more talkative, need less sleep, and have difficulty concentrating or focusing on one idea. Additionally, when their mood is elevated, they often feel like they have more energy to accomplish different goals.
