if you fear death, try to understand what it is about death you fear.
i used to fear the dentist because he would hurt me.
i used to fear injections, but that was left over from childhood fears. now i give myself injections and they hurt like i thought they would.
death is so unknown, we attach something we understand so we will think we know what there is about death to be fearful. being alone, not knowing if you are or are not, having l;ots of pain, pick the one, if you can isolate the one idea that you have about death, that you fear.
then you will have something to deal with and hopefully eliminate.
