Well, I know the topic is vague, I'm still unsure about it. I'll try to figure it out soon, or maybe it can just be "a self-healing process."
How am I going to do it?
I think so far I've read books, and write down my thoughts, opinion, emotions..., these are not enough, I know, so I guess I'll find someone to talk to or ask people what do they think about death or something.

Recently I have some weird thoughts.
I was thinking that the reason why I choose this topic is because maybe I just want to prove that I didn't forget her or it's because I am afraid that I'll forget her, but when I think of my presentation, my topic, I'll think of her. I can keep all these things in my mind, also things about her, and so I won't forget her. Maybe "let go" is more appropriate than "forget," no matter which one, both of them are difficult to complete. "To let go or not" maybe can be a topic, too, I guess. Everyone have difficulties to let go something, it's really difficult to dust off only the bad parts in our memory. I'm still working on it.

Task

Possible Topics:
*How to face death?
*How to face the pain of losing someone important?
*To know what people are thinking when they know they're going to die.
*The change of one's thoughts or emotions before/after the loss.
*The way to help yourself or others to walk through the pain of loss.
Main Idea:
Because of my terrible experience of losing my best friend three years ago, something has changed. I have changed, so to me, everything has changed since then. I am kind of still really can't control the situation, and get lost inside my mind. Sometimes I really am confused and not knowing what I am doing, so I want to know more about these kind of things and try to make themselves feeling better.

Personal Experience (Observation) I

Recently, I have been busy in school stuff, so I was totally exhausted when I got home.
Tiredness, is something I don't like, because it makes me fragile, it weakens my mind. Lots of thoughts, memories, things about what had happened rush into my head. No warnings, no notifications, they just flow in my brain, and they occupy every corner of my head. They make me breathless.
Just like the quote said, "I hear some rustle of things behind my sadness of heart─I cannot see them."
Sometimes the contradictory feelings mix together, turning into a great stress that confused me, and make me depressed. I don't even know what I did whenever I was stranded in my own complicated mind.
I guess I could just find a way out by myself, before that, I'll just repeat all above again and again....
