First off, let's not over-psychologize this. "Phobias" are by definition irrational fears or aberrant psychological conditions; death is something every human being stands to be confronted with, and anxiety over it can take many forms.
Let's also make clear that it's not necessarily death itself that our fears and anxieties attach to, since we know very little about it for certain, but there are other reasons one might be anxious over it, like the prospect of ultimately being separated from one's loved ones with no guarantee of meeting again (or more broadly, that any intimate relationship one establishes in this world is doomed), or worries that one will have lived and died without any sense of meaning for it all.
As you may have guessed, though I usually don't think of it in terms of a 'fear of death' - the things I described above (fear of loneliness and meaninglessness) do bother me, and honestly I find anyone who does not seem remotely concerned about them to be the strange ones.
That said, I don't get the fetishizing of death that is going on in parts of this thread. It does not give our lives meaning - if anything it presents an obstacle to meaning - if our lives have meaning, it's because we will give them that meaning, *despite* how death presents itself to us. All this "without death we'd have no drive" nonsense is just a convenient and not very convincing story one can tell themselves to help cope - nothing more. Besides the odd contemplative moment, most of us live as though we were totally oblivious or indifferent to death. Unless you're going to tell me you're somehow living some heroic life of great meaning a cut above that of the average modern man, then such rhetoric is empty.
Anyway, I try to deal with this by seeking out others with similar concerns and seeing if I can't make them my companions in the search for/creation of meaning. I regulate my activities, as much as possible, with a view to finding opportunities to encounter such people. Basically, I'm looking for a sense of direction in life that can justify it. It's not a real 'cure', that's just the only way I know of for dealing with it besides taking the blue pill (figuratively, possibly literally).
