Or does it?

I know we were once nothing, but it is still terrifying and depressing to me to think about returning to this. In fact, as of late, I've been unable to not think about it: the loss of all experience and all memories of everything, forever. All the good times we had, and will have, with anyone or anything ever will totally annihilate into nothingness. All our efforts will amount to nothing because the thoughtless void is ultimately what awaits everything in the end.

The only argument against this would have to be supernatural, like another cause of the Big Bang or somehow proof of reincarnation, but if my consciousness won't exist for me to experience it, then what does it matter either way?

There is no comfort in Hell, either. The anvil of death weighing down, infinitely, on all values and passions is becoming unbearable for me, so I could really use any potentially helpful thoughts about this matter.
