Comparing ourselves to others is common but unhealthy.  The same goes for MS.  When we compare our case of MS to someone else, it can mess with our heads.  MS is a very individual condition and each person's course is different from another.  How do we deal with this?  Do we feel guilty if we are doing better than someone else? Do we feel sad if we are worse?  I think the best we can do is not to compare and manage our MS as best we can.
