great insight. i too have had those same feelings, however from the other side of it. dealign with cancer has definately forced me to face those questions head on.(by they way, i am sort of in remission, so it doesent look like i am heading anywhere soon!

) instead of fighting the thought of death i am more at ease with whatever comes. also, the practice has shown me the importance of now! LIke you said it is still very difficult and it still does stress me out there is no question there, but this practice has helped me to not dwell on it and to take the good and the bad as it comes. the hardest part for me still, is how to deal with those around me who suffer becuase of my "suffering" i.e. wife. family, friends etc. who do not or are not into this practice.
