Living Deeply?

"People living deeply have no fear of death."
~Anais Nin

What exactly does "living deeply" mean anyway? I feel like I live deeply, or to the fullest. Is that what that means? I have a fear of death. In fact, I'm very afraid of what happens after you die.
I guess thats kind of silly when you think about it. To be afraid to die. When I was little I always used to think about what happend. I pictured myself looking down from Heaven and watching everything. I didn't have a normal body; my body was like clouds or something and I could see everything that was going on. I didn't feel anything and I didn't think anything. I just stood up there and watched.
Actually, I dont feel that I'm living my life to the fullest. I always worry about the silly little things that dont really matter all that much; you know, the things that mean something for those crazy intense ten seconds and then become nothing when the next big crazy thing comes along. I worry about the future wayyy too much; about where I'm going and what I'm doing and stuff like that. Now that its time to fill out college applications, I get all worked up and freak out when I start them and end up not finishing them. I only finished one. I have about five to do still. I feel like school is getting harder, things at home are getting insane, and I barely have time for anything besides school, college stuff, and the occasional meal. (JUST KIDDING ABOUT THAT. =]) But really. I'm basically freaking out about the future. =( I guess thats the stuff about being a senior that my parents left out.

Maybe living "deeply" will help all of this out? Maybe.
