I feel like giving up.

I feel so defeated. Results suck. Fuck O levels. It's ruining my life. I feel so tired, so tired. It's 3 weeks to O levels. People say when they get bad results, they will gain motivation and work even harder for the next paper. But why isn't this happening on me? I feel even more shag, even more unmotivated. Looking at all my friends around me improving in their studies make me feel super proud of them. But on the other hand, it makes me think if I'm not doing enough, if I'm not putting enough effort into my studies to make dreams come through. I'm not asking for really great grades. I'm just looking for results that I'm satisfied with. Honestly speaking, I didn't put in my 100 percent for this prelim. Since so, why am i still so sad about my results? Is it because I've higher expectations of myself after prep exams? Urgh. After all this ranting, i know life still goes on. I can't do anything about it, except to work hard, can i?
