When I was in 11th class, I was suffering from depression for 2 months.
I did not tell anyone about this.
To get out of this, I used to go out on the highway every evening for a walk and try to feel the joy and sorrow in the things around me to know how small this is my problem.
At the same time my attitude started towards spirituality.
At the same time, I read the Gita, it answers all the questions in life.
I did not read whole Gita, I read as much as I needed and then I got out of depression without any help from anyone else.
Sine then I believe that Gita is the mother of all religious books.
Depression is dark side of pain.
