I went through the exact same thing. Became depressed, unmotivated, and pretty dormant for a few months...
I had started getting really into philosophy before that, which is what eventually lead me to that belief system. Philosophy, in the end, is what saved me from all that.
I started to realize, and I'd explain this better after a spliff but whatever, that as humans we only have the ability to perceive our unimportance in the universe because we have a brain systematically powerful enough to do so... We're a blip in time, a tiny little particle, our whole planet, solar system, etc. is just a little piece of an enormous, immeasurable mass of energy.
What you have to realize is that everything exists as one. When you die, and your kids die, and their kids die, and the planet dies, and the sun dies along with our solar system, your still there. Just because you have no physical form in which your consciousness can perform action doesn't mean you aren't forever part of this huge endless ball of energy.
What's really bugging you is the lack of purpose thing, I'm guessing?
The only reason you feel this way is because you categorize things with and without purpose... believe me I know where your coming from; If nothing has a purpose, whats the fucking purpose??
really though, We just made up the word purpose. We just categorize shit like that. It doesn't really exist. Yes things scientifically have a purpose, but if we weren't here to categorize it as such... get where I'm going?
When it comes down to it, why do we need a purpose, or a need to matter. Enjoy your life the way our species has adapted to enjoy. It's a pretty crazy, beautiful thing when you look at it for what it is.

one more thing... we're the only planet with the ability to sustain intelligent, if any, life within out solar system. That's just another little one to feel good about,, i donno.

Anyway PEACE! and I really hope you find a way to feel good about life, existence, yah know... all that jazz.

p.s I don't know if you ever have, but if you ever fall in love, like, real honest to goodness just shit your pants kinda love, everything your feeling right now will be... null.
Canadien. Reviewed by Canadien. on . It's been a rough few weeks Ever since my friend's mom died, I've been beyond depressed... Hell, even before it happened. I find myself focusing more on the inevitablity that we're all going to be a sandspeck in the beach of time, and it feels like everything's just too big for me. I find myself becoming much more disorganized, more tired, I have more pain, and I just don't feel the way I used to. I go from each day thinking "Oh wow, the world's such a beautiful place" to thinking "Nothing really matters, not my Rating: 5
