Depression is like sinking into darkness.
A person, suffering from depression, looses control of his life.
It may be surprising, but the reality is this, that because one looses control of his life, one is depressed.
How we lost control of our lives? Society wants us to be obedient, because it wants us to be utilitarian only.
Society never bothers about our growth & happiness.
And because we are dependent on the society, we start following the instructions given by it.
For most of the cases, everybody wants to control others.
A husband is trying to control his wife & a wife is trying to control her husband.
A father is trying to control his son & the son is trying to control his father.
Every body is trying to control others.
  Looking at the reality, nobody can control others.
The only person, one can control, is himself.
Some body may tell it that, he is depressed due to his wife or his son or his father or some adverse circumstances.
But the fact is that nobody can hurt you without your permission.
  One, who wants to come out of depression, has to accept the total responsibility of his life.
We are responsible for our lives only.
We are not responsible for behaviors of others.
And as we accept this responsibility of our actions & reactions, the problem becomes simple, as now we have to change our habit patterns only.
  The only impossible thing in life is to change others & the only possible thing in life is to change ourselves.
  If we want to come out of depression, we will have to take the charge of our life from right this moment & work on ourselves to take control of our life.
