How to know what I want from my life?

I am really finding it hard to know what my real likes are? What I love to do? I am just fed up with myself continuously doing things as I am directed to do, maybe due to the parents, due to the society and in all this, I have lost myself, its such a pitiable situation that now I don’t even know what I really enjoy or like to do?
I have not been able to sleep from the past couple of days owing to this great sense of discomfort that I am facing, somebody help me please.
