Bipolar disorder is a psychological mood disorder that causes an individual to experience extreme shifts in mood and personality. These mood changes typically cause a person to experience manic periods followed by depressive periods. During a manic episode an individual may exude high levels of energy, a lack of a need to rest, and the need for constant activity. On the contrary, depressive episodes involve low levels of energy, a constant need to sleep, as well as feelings of hopelessness and sadness. Managing bipolar tendencies is essential to seeking balance, controlling your emotions, and improving your social and relational interactions.
