[bobish]

detail plz*? im just curious as to exactly HOW this dying happens? do they die in pain like screaming a horrible death or something? or slip away silently and no one even knows?
just curious cuase my dear friend is at the end stage it looks like from what the DRs said...i just dont want them to suffer pain in the last moments. so will they go in extreme pain in the last moments? or slip away quietly and peacefully?
and past expereinces from watching or hearing of ppl die from cancer? liver cancer? or any cancer?
sorry i have to ask this, but im just worried
