Personally i think my fear of death revolves around two things, the idea of it happening before i do some things in life, and a general discomfort with the idea of losing control, which i kind of view death as a form of (the most severe form, probably). Specifically, the loss of control is not perceived as something that happens after death, but in the sense that if i'm dying and i'm aware of the fact that i'm dying, i would be pretty helpless. Something along those lines, but more detailed than that.
Anyway, sometimes i feel comfortable with the idea of dying when i think of it without some of the above extensions (or others), but some other times when i imagine specifics such as dying and being aware of the fact, i experience a type of fear that rarely comes from anything else. Whether it's me or somebody i care about, death can come at any time, in anyway, and eventually it's gonna happen and nothing can be done about it, whether someone was ready for it or not, and on top of all that it can come in very unpleasant ways.
Ideally, i think something like that just needs to be accepted, because there's nothing else to be done. It's the most positive outcome i can hope for (to accept it), and so basically the way to address it from my view is to either make sure i'm on my way to doing the things i want to do in life, trying to address my fear of loss of control, and generally just not worrying about it (or not thinking about it often), particularly when it comes to others because there's little to be done, or, basically make sure i don't allow myself to get attached to life or anything in it beyond certain points, which would be points vastly minimal compared to my current investment in life and in others, so that i won't worry about losing any of it.
Where i stand seems to be kind of in the middle between those two options. In my mind, i want to do things like i described in the first option, and somehow do in some regards, yet my actions still seem somehow leaning towards the second. I'm trying to stop that from being the case.
