^what a girl...
Back on topic people!! We're not going crazy just because we think about death! Everyone does it... (now it sounds like I'm trying to get you to do drugs!)
Anyway, who knows what happens when you die... it's impossible to tell until it actually happens to you and then you can't tell anyone else what you learned because, well, you're dead. It's scary not knowing what's going to happen but it's a feeling we all, unfortunately, have to deal with.
