A psychologist years ago said somthing to me I will never forget. "Just because you are paranoid, it doesn't mean they aren't really out to get you." You are hardly neurotic, you are behaving like a perfectly normal person with "cancer survivoritis". And your emotions and concerns are both normal and appropriate for where you and your husband are ihn the process. I can only tell you that as the years pass from the original event that this becomes less acute, but in my 5 years, it hasn't gone away completely. Perhaps some of the longer term survivors can offer insights into when in their own lives this gets to not be part of your daily thought process.
