Contents: Anxiety vs Depression
Anxiety is characterized by a sense of fear, doubt and vulnerability about future events. The attention of anxious people is focused on something in the future, and fear that it will be bad.
Depression is not characterized by the fear and uncertainty that anxiety is. Depressed people are not as anxious about the future, as they are dejected about the present, mostly as a result of something that has occurred in the recent or remote past. They don’t expect anything different from the future and may often assume the future to be as bad as the present, or think there's anything worth preventing.

Some of the common types of anxiety are panic disorder, social anxiety disorder, obsessive compulsive disorder, generalized anxiety disorder, post-traumatic stress disorder, and specific phobias. Panic disorder is characterized by a feeling of terror or enhanced worry. Obsessive compulsive disorder causes people to indulge in obsessive behaviors like washing hands frequently, arranging desks or closets, cleaning dust, etc. Social anxiety disorder or social phobia pertains to the fear of being ridiculed or embarrassed in public. Special phobias could be fear of insects, height, water, fire or flying. Post traumatic stress disorder happens to people after they are involved in some natural disaster, accident, physical or sexual abuse. Generalized anxiety disorder is excessive and irrational worry about anything.
The most serious type of depression is major depression disorder, also known as clinical depression. It can seriously inhibit a person’s capability to work, study, eat or sleep. This depression can have drastic effect on a person’s quality of life. Another prolonged type of depression is dysthymia, which is comparatively less serious than major depression but can impact quality of life too. Another type of depression is bipolar depression which is marked by dramatic mood swings, depression and maniacal thinking.
Both anxiety and depression are caused by chemical changes in the brain, specifically the neuro-transmission function. Low serotonin and levels of dopamine and epinephrine are responsible for anxiety and depression.
edit Treatment Options
Anxiety can be treated with the help of psychotherapy, cognitive behavioral therapy, stress management exercises and medications.
Some of the same treatment methods like psychotherapy, cognitive-behavioral therapy and medications can also help in depression but serious depression may require ECT (electro-convulsive therapy), rTMS (repetitive transcranial magnetic stimulation) and hospitalization.
Some of the medication prescribed for anxiety and/or depressive disorders include Lorazepam, Alprazolam (Xanax), Clonazepam (Klonipin), Diazepam (Valium), Prozac and Zoloft. The medication depends on various factors like the type and severity of disorder, the patient's response to the medication, other harmful side effects, among other things.
