Death. Because people just can't seem to stop pressuring on me and to Leave me alone and I'm sick of everyone's manipulation and judging me with no reason. I constantly have stalkers behind my back. That's why almost everyday I wanna die,cuz I seriously can't take this pressure.
Life, I'm always thinking about my crush, about school and stuff like that :) I think about death only after I watch an episode of Grey's Anatomy -I'm feeling like I have all the deadly diseases in the world :)).
I often take some time to just sit down and contemplate the series of events that formed my life. I've had some rough experiences, touching experiences, joyful victories, emotionally straining times, and times where I wanted to even end my life during my past fourteen years of living. All events contributed immensely to the person I am today, and perhaps to the person I will become in the future.
I always think that before I make another big step, which is adulthood, I need to reflect on what has happened. So I..guess I analyze my experiences, figure out what I should have learned from them, and if others are just simply horrible, try to find something that I can walk away with and later on use as an advantage.
For me, life is based on learning something. It's shallow as hell because of people (some of the people), but exceedingly deep because of experience at the exact same time. Which I guess is one of the reasons why I find life just so damn confusing :P
So, to answer your question, I guess I think about life. Death is just a whole other mystery to be unraveled, and will have to wait as of now. xD
