Big failure.

I am the biggest failure I know of. I feel so dumb right now. I've had so many sleepless nights okay? And I am SO SURE I studied for that test. I know everyone did OKAY but why does it seem like nothing is working out for me? I've tried everything but I ALWAYS, ALWAYS, ALWAYS fail. I'm pretty sure I'm included in that half who needs to take removals. 

I'm losing all hope. Is this really for me?
