Right now I believe losing someone I love would be the worst of those listed. I may have found that "one true love" and, though currently nurturing it, the part of me that thinks this would be devastated if I lost it. We are both thinking the same way, and are loving our journey together. After all these years of not knowing that it is actually possible to attain, it may be too much of a loss to bear. I can stand on my own, but as that dream becomes real, I won't let it go.
Since everybody seems to comment on the others: public speaking is no big deal; loneliness - been there, done that; darkness - not sure about what it means for this poll (going blind would suck, becoming evil would be a transition I would obviously believe in); death - I am looking forward to it, but only when it is my time. I should hope that when it happens, I will know, and can have others be present with me when I cross over. If it is instant, then I hope for a big party after the funeral. Celebrate what was, to support what could be.
No need to fear death because we are born knowing that we will one day leave here. Public Speaking use to terrify me but I realized that I just don't care anymore. Loneliness doesn't bother me because in solitude there can be peace. I use to fear losing someone, but in five years I've lost my mother and my father... and I no longer have a need for that fear.
I fear fear itself... fear is a cold, hard, and lonely emotion. It isolates you internally from the truth and keeps a hold on you for as long as you allow it to do so. I strive with every fiber of my being to conquer my fear whenever I recongnize it creeping into my life. It's a daily battle that lessens with time. - Embrace the Unknown.
I do not fear death nor darkness, they are natural aspects in life. Public speaking the old me would have died doing but I have since conquered that. Loneliness is sometimes the one thing I need to gather thoughts and reboot. I do fear losing someone I love and was forced to face it when my grandmother died.
However, what I fear so much of is myself... To know that I am in control and I alone can be my greatest downfall. I drown in my fear.
