That is a question that I asked myself many, many times. I am not against the idea of finding the will to live once more, but I just can't think of something, even if a magical wand could grant anything, that could change my mind so much that I wouldn't be willing to go away.
I still continue to ask myself that from time to time, maybe one day I will find an answer even if I don't think that will happen. The only thing I could answer is "being a completely different person, with different ideas and feelings and ideas", but that is equal to the death of what defines "me", so it doesn't answer the question.
