On the subject of life and death

I've been thinking lately about death. I've grown into a state of depression over the subject.

Before we were born into life, we did not have a concept of time because we did not have brains to acknowledge time. There wasn't complete darkness or anything. As we grow older and develope our brains have now understood this and it's own consciousness.

Is this what it will be like after death?
No complete darkness, no heaven, no hell, no reincarnation, nothing.
We will die and our brains will stop working and that will be the end of it.

It's an incredibly scary thought, but fear is just a primitive emotion in response to a human's environment to flee a situation for survival.

I just see no reason for going on.
Do I get a high paying job, so I can be happy? But happyness itself is just another emotion. When a human's environment and surroundings are suitable they take joy in these things and have a desire to keep them, much like loved ones.

So my sole purpose in life is to just pass on my genetic material to the next generation to form a more perfect species. I will die and there will be no concept of time. Life just seems so incredibly pointless and I have no desire to continue it.

Before you look for new answers, review the answers you already have.

You exist. So obviously you should do something.

The fact that you don't know what you are with any certainty. Yes we are a brain/computer, but why aren't we just a soulless chain reaction? how do we percieve? Therefore don't give up hope yet, there is something going on, we just don't know what it is.

I could go on and ponder science, existence and sentience etc.. There isn't much point unless you want to be more specific. Don't fret over unknowns before you've even considerred the obvious and since you exist you might aswell do something.
