A lot of people who are depressed and only can no longer cope with their usually activity every day.
This is because they cannot think of an appropriate way on how they can solve their problem.
This is not actually a physical health problem.
It is highly related to the emotional and physiological health.
If stress and anxiety cannot be solved, there is an assurance that the person might do some suicide attempts.
The main causes are drug and alcohol abuse, abuse, severe stress, death of a family member or a love one, stressor at home and in the office and more.
In fact, people who are depressed, rely on various anti depressant drugs.
However, the effect will only appear after two to four weeks.
Usually, the physician will not be prescribing any anti depressant medication, unless the person really needed it.
As much as possible, they do not want the person to be dependent with the drug because of its bad effects.
There are a lot of natural techniques that can be done.
A depressed person should not isolate him or herself because it would be better if they will interact with other people.
Sharing thoughts, feelings and concerns are one way for you to reduce anxiety and stress.
It would be better if you will be diverting your attention and interest into something that is positive.
Perhaps, the causes of depression might be very common and general.
