I feel lost. How do I find my purpose.

I feel so lost. Spending Saturday Sunday at room. Dont know what to do. My work no longer attracts me. Why should I keep working? What else I can do beyond weekday work to make my life more fullfilled and complete? Life wasn't this bad, it started when I moved from India to Holland for my work. Should I leave work and go back? I dont know what I'll do after going back. I dont see any purpose in my life anymore. I dont have any definite goals. I can't prioritize important things in life? What is important in life? How do I get myself out of this bed, feel happy and get myself to do something?
