I think there are 3 modes of me

I am different in mornings, afternoons at night. Somehow I think that makes me Bipolar but then of course I wouldn't jump into conclusions like that.
I am the most productive in the mornings. It's the time of the day where I would make up all sorts of ridiculous plans and try to fulfill them. However, I am also not a morning person and for most days I feel so tired in the mornings that I seldom accomplish stuff that I need to do. So in the mornings, I would wake up early to write in my planner and then either sleep in the library table or continue sleeping in my bed. I know I sound so lazy and no, caffeine doesn't help. Somehow my body has an odd way of processing caffeine to only make it work at night, when I really want to sleep.
I am hungry in the afternoon. There's lunch and tea time and dinner and I could have just have them in the afternoon within a few hours. I am productive before lunch and I will normally make my lunch time to be as long as I could so that I could actually do something but somehow my stomach grumbles really loudly and the silent part of my brain will go "EATLUNCH EAT LUNCH/TEA TIME/DINNER"
I am always nostalgic at night. I will think about everything that I've done in the past 18 years at night. Although I cherish these thoughts for self-improvement, it sucks that these feelings will always go out of hand and I will end up with insomnia and hence the sleeping-in at mornings. I have a need for hoodies and blankets at night and shows/movies/TV episodes are a must. I seldom get any studying done at night because I'll get tired after dinner and will yearn for a nap. A NAP. I will wake up at 1 a.m in the morning automatically after the nap.
