I prize my brain greatly. I'd rather die than lose the ability to think meaningful things. (i.e. I'm glad lobotomies were banned.)
Well, the best way to not fear death is to become cynical and jaded (like me) and think that the world and society today is a pile of crap and that there are only a few good things worth living for. That's a sure way to become less fearful of death.
Sorry, that was me being sarcastic
Anyways, just don't give up. What if Einstein had let thoughts like that overpower him? What if (heaven forbid) Chopin did? Where would we be now? From a "humanist" perspective, the meaning of life is not to have lived it, but to have done something with it that outlives you. "Merely to live, merely to exist; what sense is there to it? A fly also lives."
Don't take that the wrong way - don't go around destroying and bombing things (which is what humans have been doing for the last thousand or so years). I'm sure you have the good sense to figure out what I mean by what I just said!
I think that your primary reason for fearing death is that you are afraid that your life will be transient and ephemeral, and have no real meaning. It's completely up to you not to let that happen!
If it gets too bad, you'll likely need some medical help. I might be qualified to provide that in 10 or 20 years!
