Sleep Deprived, Frustrated, and Over-Caffeinated

It's only a week--days worth of journey for me to finally reach the start of my national exams. Fun, fun, fun! With the amount of stress and pain these three years have given me, I might actually be able to pay it all off after I do this one obstacle (that, and getting into the university that I want), despite the fact that I'm actually scared shitless and anxious of what's to come next. I'd love to explain why, but I'm afraid by doing so would just cause a long post of rants and complaints that will mostly send me into another state of breaking down. So, let's just get to the point, shall we?

I don't even know what's the true point of writing this post--I just feel like doing so. Now, for those of you who doesn't know yet, even though I've stated the obvious up there; I'm a twelfth grader who's about to graduate (amen) and moving on to university (also amen), aka another whole new level of educational and adultery hell. These three years, I've spent most of my studies in english, a requirement because after all, I'm an international student. I have taken IGCSE and AS Levels, in the earlier years of high school, and now I'm adapting back to the Indonesian curriculum for the national exams.

One of the things that I recently just found out that's related to this topic is that I'm actually more focused and determined to study when it's late at night; and by this I mean like--very, very, very late at night. The time of my brain's activation varies from 11pm-1am and I'd usually stay up late until I have to go and prepare for school.

Now, I want you to imagine how very tiring this fucked up schedule of mine actually is. From morning to late afternoon, I have school. After that, I still have to take extra courses until 8pm-ish. Trying to attempt a nap or even to sleep is very risky, 'cause I'm not exactly a person that'll get up that easily, so, I basically just stay up and try to watch and catch up with my shows until the clock indicates that it's somewhere around 11-12, then I'd prepare things and go study. Where does my sleeping schedule fit in there? 
With this happening very often, how do I fuel myself? That's where caffeine comes to the rescue. I've asked my mom to stock me with carton-packaged coffee that'll last for 3 months for a normal person, but with the amount of sleep that I'm getting, I could finish it in a month and probably less. My blood is pretty much made up with 50% of caffeine right now. Now, what surprised me is that one time, I was so hooked up on coffee, I keep taking it and the caffeine tended not to work on curing my... sleepiness. If anything, it'd only make me more sleepy. Now, when this happened, I've also kind of figured out that alcoholic beverages are helpful when I needed energy push, but it's practically impossible to stock me with liquors just to feel energetic, so.

What bothers me is that I'm just super tired and done with anything educational-related that I'm more looking forward to the long vacation after this exam is over instead of the exam itself. I'm just casually waiting for it to end, to pass, so I could finally be free to do whatever it is that I want to do. Sleep, binge-watch TV shows, hang out with friends, anything, really.

Just--wish me luck and pray for me. Feels like (but hopefully not) I'm gonna need it.
