Write your own fate

I don't know whether that happens only with few people or there are so many who face that situation. In fact I don't even want to know.
For me its a bitter truth of my life. It's a situation when you convince yourself to believe that you also have something called as Luck and you are Lucky to have in general an easy life. When you feel that you are now less unhappy than before.

At this age of life I can say that I have learned something by experience.

• As you grow, you will always face new challenges, worse that you have ever had.
• Everybody is unique in the world, so as the challenges they face.

This time its something that I have never thought of and i still not able to understand why? If I ask "why me?", then that will be stupid question. what else I wanna know is why now, why not before.
I don't know what should I do? one option may be to believe that It's all my own fault, but it will be tough as I know that it is not.
hmmm.. i think there is no other option to believe:
time comes when one has to accept that fate is all written, you can not change that.
