Those are heartfelt questions. Here's my take on why we feel dread about the idea of death even though it's universal and natural. I'm speaking purely from evolutionary perspectives here. We exist to propagate the species. Beyond that, we have no purpose. Until man developed a consciousness of his surroundings that exceeded that of animals, death wasn't anticipated. Now, it's very advantageous to have this awareness that humans have, but one of the down sides is that we can anticipate our own deaths. Since we normally enjoy life, who wants it to end? Thus the dread of death. We can see it in others and extrapolate to our own life, a unique ability in the natural world.
So it's natural, but not pleasant, and that's how they both fit. We have developed the ability to foresee our own actions, a wonderful gift that comes with a great caveat: we do not look forward to everything we foresee. Thus it's perfectly natural to die, and yet we do not wish it to be so.
"Wish" is the operative word. You even used a similar word, "want," when describing why you yearn to know a purpose. You "want" there to be more, and that emotional reaction (perfectly understandable) makes you think there must be more. But there doesn't have to be more, even if we wish it so. Wishing does not make it so. The evolutionary explanation, while not accepted by all, does provide a logically-consistent explanation for this issue.
