That's your problem, not the talking to god bit.

It's that you're craving certainty and limits in an uncertain and infinite universe.

Yeah, that or do what the rest of us do. Drown your brain into sex, drugs, music, entertainment, other people, etc, and just don't think about it.

Trust me on this. You'll be much happier.

Okay I joke, but there is a lot of truth to that. The whole "life" thing has what from all intents and purposes is an inevitable outcome, at some 'eventually' time frame. It's for most people though a pretty long time away.

Can you control it? Well.... to some degree. You can live healthy, you can make rational risk assessments of your actions, and generally speaking make out quite well, but beyond that, theres not a whole lot that can be done.

So, do what you can and then do the most you can with what's left. For many that means general straight up hedonism. Enjoy in sensations the universe has given your consciousness. You happen to live in an age where you have access to thing no human beings before have access too. Live in that. Experience all you can.

Another thing which many find great meaning in is helping other humans. We're a social species. Who we are.... is a whole lot less our bodies and minds, than our personal body processing the collective consciousness it's been imparted with. Help add to that. Do this and a part of you will live on in everyone else to come.
