Thanks for sharing, but these questions call for a highly speculative philosophical reply and are not what I consider myself to be a prime resource on. Perhaps other readers may want to join in. However, I might suggest that you focus on accepting your feelings as they are, instead of intellectually focusing on future events or circumstances. You are not to be concerned with trying to accept death or not, but what are your feelings about death? Always take it to a feeling level and work with those feelings. Most likely you have fear - so that's your starting point. As you work with / integrate fear or whatever else comes up for you, it will modify your 'acceptance' of death itself.
