rants of the fickle one

There are some individuals whom may develop mild depression, which may start gradually for no reason. The individual may start to feel tired, restless, lonely and have difficulty sleeping. In many cases, the individual loses interest in sex and wants to be left alone. One may be able to go to work but not have any enjoyment. Mild depression may last a lot longer than slight depression, but can be overcome with changes in lifestyle, psychotherapy and social support.

However, some individuals develop severe depression, which may induce feelings of suicidal ideation as it is common in severe depression. In severe depression, one may feel sad constantly, cry for no apparent reason, have trouble sleeping and focusing , become fatigued, feel worthless, have headaches or even backache . While slight depression has a cause, both mild and severe depression generally are complex disorders, which are not well understood. Mild depression may be related to the environment, such as being unable to cope with a certain job, unemployment, financial problems or loss of a loved one. No one understands why severe depression occurs. Even though many brain imaging studies have been done, the exact neurotransmitters in the brain which play a role in depression are still in question. Some studies do show that severe depression may be more common in families. Although the exact causes of depression are unknown, there are several risk factors that can trigger or increase the risk of depression.
