In the Kung Fu Panda, Master Oogway told Panda, "you are too worried about what has happened and what will happen. Don't spoil your present by keeping yourself engaged in past and future".
Second, last year, I was having discussion with a senior citizen on my CSS preparations and the subsequent pressure I was carrying due to it i.e. expectations. After listening to me, he replied, "this pressure of performing good is a key element to make you grind yourself better".
I advice you to simply make day-to-day study plan and focus on it for 20 odd days. After that, start applying for other competitive jobs to support your family and NEVER think that CSS is the full-stop.
