There are times in our life when we really feel sick. There's nothing worth living for, and everything seems utterly boring and pointless. This is the best time for some introspection. It is also time to sit down and motivate yourself. As this is a low point, the only way you can go now is up! You are bound to rise to new heights, provided you don't lose hope. This is the start of the next big leap.
The bottom line is, believe in yourself. Believe in destiny. As I have earlier said, you cannot predict your own destiny, and so the only option is to live life as it comes. Take atleast some time alone. Sit on a deserted beach. The pieces will come together again, and you will be prepared to work once more.
