How I Know I'll Go Somewhere When I Die

Yeah, so I often get afraid of dying. I wonder if there is something after this. i believe in God but still the human in me makes me fearful that death is the end. my fear grew even stronger when i was watching the show Intervention on TV and a man who had died and came back to life after an overdose stated that there was nothing at the time of his death. No light, no angels, just death. i worried, if this man died and saw nothing, then there must be nothing.... My friend is pregnant right now. Every day her belly gets bigger and we all feel it kick in her belly and can see it move from outside. It's crazy. thne i thought about it and, no one remembers what it's like on the inside of their mom's belly. As far as we're concerned it possibly never happened. the only thing we are aware of is who we are now and what our memories consist of, but just aqs there was a before that we don't know about there will be an after. Hope I'm right!
