losing control on one's life is not a good thing. Everything will be pretty much screwed up and doesn't work out. One will be miserable and depressed.

For an example, a student found out that he did not do very well in all of his tests. He started to lose control on his time and started to lose attention on his studies. He does not know why he can no longer control himself and cannot focus on what he is doing. He lost his self confidence.
The cycle goes on until the student is trapped in this situation. He finally just gave up and decided to drop out of school.

Why is this happening and what is the best way out from this dilema?
