One of the main characteristics of depression is an intense feeling of despair or hopelessness, but this mood disorder affects far more than one's emotions. Depression creeps into every aspect of life, influencing how people behave, think, and feel physically and mentally.
Behavioral Changes Associated With Depression
Those experiencing depression don't act like themselves. They may become irritable or quick to anger. Their sleeping habits can change, resulting in more time spent asleep or just lying in bed.
Every action seems like an overwhelming chore to someone who feels depressed, so daily habits -- such as taking a shower or doing laundry -- may stop. Even spending time with friends and family or engaging in hobbies seems to require too much energy, so depression causes people to withdraw from activities and isolate themselves from others.
Depression can also cause people to behave in life-threatening ways. Committing self-harm and attempting suicide are two severe behavioral changes associated with depression that require immediate intervention from a behavioral health professional.
