Mouse,
For years I went without the fear of death, and instead was glad to think it could happen at any time. In fact I hoped it would so i could be free. I was surprised when I came to where you are now-- which is fearing death. I honestly never thought it would happen again and that I could grow so attached to life that I had anxiety about parting from it. I don't know if you've been in similar places (seeking death), but I almost welcomed the fear of death as suggesting growth on my part-- reattachment to life. I know that probably doesn't minimize your fears, and it doesn't minimize mine. However, at least I was able to spin it in a direction that helped me understand part of my illness was over or at least in remission.

I hope this helps, though I'm not sure it will, but perhaps your fear of death is like mine, signifying that life is worth living.

Best,
