I feel so dumb. I tell myself that I'm going to work as hard as I can to build a future for myself, but instead I rot in my room and let time pass. I have around 24 hours until a fairly important exam. I have done maybe an hour of revision this whole exam season. I am desperate to turn my life around. My mom wants me to get good grades because she paid for this exam. I am so afraid of messing this up. I can't turn back time, but I can stop being lazy. I just don't know how to. I can handle the truth, and the fact of the matter is I am pretty much screwing up my future if I don't stop being a useless piece of shit. I don't know how to deal with these emotions, or why I am so lazy and gross. How do I change? How do I fix things if I fuck up by failing this exam? Is it possible to turn my life around? I am so nervous...
