Is it normal for an existential crisis to give me such an anguish?

I definitely understand your anguish!
The idea of eternity freaks me out too! That's just such a horrible thought.
But really, when your body decomposes you have to lose all consciousness.... so I find that kind of comforting.

If we remain as an energy, then we must have been like that before birth and I don't remember that being bad, so I'm sure it's ok...:)

And if there is no point, or we're just minds controlling these mammal 'robots' that only exist because they found the ability to reproduce...then well.... Well I drink, but I know that's not good advice! Just enjoy it I guess...
