A reader writes: Over the past 3 years I've lost four close friends to various types of cancer. It's been hard for me to deal with this adversity, but I have an especially difficult time with the fact that when someone dies I feel very sad about them dying and then if someone else dies, the more recent death seems to consume me and I forget just how painful losing my other friend was. I want to remember all of my friends so I feel guilty for letting the pain associated with their death leave me to be replaced by another. Is this typical for someone like me? Just wondered. Thanks.
