A sense of failure

   I failed my CFA exam
   I don't know how should I feel anymore, even though I did prepare for it. And writing about this makes me feel like a sore loser.
   It's like getting pass all kind of exam shits is one of the few things you are really good at, and this time you don't even make it right.
   I can make myself a tons of excuses to make me feel better, but deep down inside I know it's me the one to blame. If I try harder, spend less time on bullshit things, or be more hard-working, I'm definitely can pass. But I didn't, and this time the god of fortune is not on my side anymore to cover up for my laziness and stupidness . The problem is I never did fully concentrate in my life, for ANYTHING, to get the highest result I can. And now the first consequence comes up. So what should I do next? Taking the next one in June, or only do it again when I'm really change and be well prepared for it?? Really sad, confuse, frustrating right now, like I don't want to do anything since I may screw up something else.
    The first failure feeling doesn't feel good at all eh ?
     I let many people down, the friends who help me at taking it, my mom for wasting her money for nothing, and so on...
    Really lost right now, hope I could figure out something after getting through this.
