Death is something that always creeps around me. Virtually all of my male relatives and one of my best friends from college are already dead (oh boy).
It's gotten to the point where I don't really even get that upset about it anymore - it's to be expected. We'll, and everyone we've ever known, all eventually suffer the same fate.
Generally what I do if I'm feeling especially shitty, is sit down, and write out everything that I can remember about said person. Usually it's very stream of conscious-like, so as to attempt to recreate that person as best I could - as if I were attempting to write an actor instructions for a film. But in general that was something I mostly did when I was younger and death was more shocking to me. Generally only 10-20 minutes of that is required to get me back into my usualish mood lol.
Now I just go down to the liquor store, buy 2 40's, and make a day of it. I also tend to repeat that ritual should I remember the day (there are 3-4 folks I remember in such ways). I find not really talking about it and just numbing myself to my emotions is best for me. Video game and booze binge basically lol. Then it'll pass as acceptance creeps in.
My dad died when I was 4 - which pretty much was the end of my childhood and mom never really recovered. All of my male grandparents have died, a grandmother, one of my best friends (a cousin) committed suicide when she was 16, and one of my best friends in college randomly got pneumonia and died shortly after graduation. Each instance has gotten progressively less traumatic - sad in its own way I guess.
