I think that now I just try to control the controllables. Live a good life, do no harm, help others, etc. I'm not afraid of death, as I've been there once already, before birth.
With that said, I personally do have a struggle with loss. The interesting thing is that I struggled for my first 38 years of life or so with suicidal ideation as a JW. If I died, that might have been a relief. But now I have a life that I'm in love with, and just like the thought of losing my wife, the thought of losing my life does kind of always loom and makes me sad to think about. It's the beauty and curse of having something great in an impermanent world. I do struggle with unwanted thoughts due to that though.
