A sense of hopelessness... making me feel like giving up and then hating myself for not studying....?

Last yeah I had a major exam and kind of studied last minute. But it worked out and I managed to score all distinctions except one B. Since then I've been really taking it easy this year. After new subjects were introduced and I went into a pure science cl where my syllabus were more specialized in my high school. Anyway my end term exam is nearing in 11 days and I feel like I've just effing my whole year up this year. Its like I've just been taking it easy as hell. I have dreams to be a staff photographer for Nat Geo, and I try to use it as motivation to study but it just doesn't work out. I've been failing my maths and history and getting C's and D's for my other subjects. People tell me that this year isn't a 'honeymoon' year even though my major exam last year was over and that this year is actually the foundation for my GCSE next year. I KNOW I should study. But I just feel like giving up as covering this whole years work in 11 days is impossible. And I hate myself for doing it. I know I should do what I can, but I feel so pathetic and its like i'm just wallowing in self pity. And then I hate myself more for being like that. I just got screwed badly by my dad a couple days ago when he finally found out my results this year from my mom. He made a time table for me to study this last 11 days. I followed it yesterday. But now that he's outstation I'm on the computer. I hate the fact that I'm just complaining and doing nothing, but i'm honestly just at a lost. I feel like just curling up in a ball and sleeping. Either that, or just hanging out with my friends. I don't know what to do now. I don't wanna regret it later in my life as I do have a big ambition, but you know what they say, vision without actions is merely a dream. I'm feel like a ******* screw up at the moment.
