Being born can be compared to a one in billions lottery win. We're given this time. "All we have to decide is what to do with the time that is given us". I hope you get to feel more positive about being around.
My belief is, when you're gone, you're gone. All this religion and quantum mechanics speculation about coming back is wishful thinking (it's one reason religion is so powerful. It's very hard and scary to comprehend our non existence. Religion provides a nice candy wrapped solution to all that.)
