I've become a nocturnal

!Just a rant. Ignore if ydgaf!
So this has been going for like a month now, i can't sleep at night anymore. I can only get sleepy at 4 am and it's driving me crazy.
I've missed several classes but this will be the 3rd time i missed my accountant offline class and THE THING IS i was already woken up by my alarm at 6.30. I swear i dozed off just a LITTLE bit. Wakes up again at 9 am. Of fucking course.
I decided change my sleep/awake schedule with me going to sleep at noons, around 3 pm and then going to sleep at 11 pm so it's still 8 hours of sleep. And then i'm gonna be awake from 11 pm until i'm basically done with school and shit.
I'm tired of missing class and i feel extremely guilty cus my parents are paying for this and all i do is, fucking sleep. I'm planning to change uni anyway but i don't know if i'm gonna pass the entrance exam so i shouldn't be fucking up my absent like this.
This is so gonna be great and totally not unhealthy lmfao
