Atheism is very, VERY hard.

[Clueless Morgan]

I can't deal with the fact that I'm just going to die.

Everyone is going to die. The question is what happens after you die? Something? Nothing? In either case all you can do is live the best life you can live and let the chips fall where they may. If there is a heaven and you lived a good life, you'll get in. If there is a heaven and you lived a good life but don't get in then the arbiter of that heaven isn't worth spending your eternity with. If you lived a good life and there is no heaven than you lived a good life and there's nothing to regret about that.

I can't deal with the fact that when I'm on my own, I'm truly alone and nobody will be watching me from above.

Even though there is no super dude looking out for you just remember that you have something so much more powerful and worthwhile: family and friends that love you.

And now you have your AF family.

Without religion, where's the moral code?

What if this god dude is real? I'll be in hell. Hell is scary.

Like others have said, fear is a powerful motivator for believing in things that aren't true. Just remember that there is as much evidence for the existence of hell as there is for the existence of Mordor: a book. Nothing more.

I want to debunk the myth that all atheist are depressed because they're lonley and will just turn to dust when they die.

You only turn to dust if you're cremated. Otherwise this is what happens (assuming you're not embalmed):

I will spend my life, for better or worse, taking from plants and other animals in order to sustain my life, and when I die I get to give myself back to them so that they can sustain their lives. What could be more glorious and more fitting than that?

Sorry this is really long, thank you.

nort: Go find my introduction. :p
