Extreme, unhealthy caffeine habit. iin?

I'm a 15 year old male person, and I have this odd pattern of behavior which starts every other day around midnight, when I chug down 8-12 mugs of black coffee. I then experience a powerful rush of energy, sprint around the block 3 times, do 50 pushups, and pace around throughout whole house thinking intensely about various personal, philosophical, and scientific problems and ideas while snapping my fingers compulsively and talking to myself at random moments (often cursing out loud like a madman). After a few hours of this, I sit down at my desk, do all my homework, put on some music, and read a book until the sun comes up (usually a textbook on something I'm into). Around this point, I start to crash, becoming too tired and dumb to read my book anymore, so I take my laptop into bed and read shit I only half care about on websites which I forget how I found. I eventually put the computer down (usually around 8:00 AM) and fall asleep with a narcissistic sense of accomplishment.

The next day I wake up around 3PM with a headache, feeling exhausted, depressed and thirsty. I usually drink about 1-2 mugs of coffee just to fight off the headache and hang on to my sanity. This day usually consists of sleeping on and off, avoiding my family, masturbating, and thinking repetitive thoughts of self hatred.

There is usually an intermediate day during which I am what I consider to be my normal self. On the next day, I drink my ridiculous amounts of coffee and the whole thing starts again. I know that none of this is healthy, but is it normal? Do any of you do this or know anyone who does this?
