No Motivation

I'm at my new year of college and to tell you the truth...its the same thing as highschool. The only difference is that the teachers are crazy and there is a lot of work. But I'm starting to feel like I don't care about the work or my grades...I do my works but at last minut or in test I study a little. I don't know what to do. I know that I should do something about this problem and I know that I need to change but...I just don't care. I have no motivation to do my things. Tmorrow I have a test about pfisics and I did not study at all (good thing the class is at 1:00 pm) and insted of doing that I'm writing this and chattin on FB. I told my mother it did not help because she doesn't know what to do either.
I don't see my future.
I'm only living in the present.
I have sat down and just think about me and what I want...
But I don't want anything.
I need help.
Help please....
