I just miss myself even though I'm still here
Yeah- this. Sometimes I miss or mourn who I think I had the potential to be. But then, I remind myself why I'm not and why I don't want to put the effort in to try to be that person now.
But no, I hope when we're gone, that's it. That's the main appeal I suppose. To no longer have desires you can't fulfil.
If there happens to be an afterlife- I suppose you could miss your life on planet earth. That only seems likely if the afterlife is worse! If hell is real. Or, if we have different 'bodies' in heaven or wherever else and we miss what we could do with human bodies.
Or- and this seems likely with what we learn about religion- we get taken through our lives step by step in some sort of tedious performance review. Like- you blasphemed on the 17th of September, 1999 at 3 o' clock. That means a reduction in privelages I'm afraid... Then I imagine we'll start to regret all the naughty things we got up to or, all the things we were supposed to learn/ experience while alive but didn't.
