I have not been able to get my hands on the info about the tape from Smart Marriages that I mentioned, but meanwhile I found a good page on managing your chronic illness:

9. Nurture Primary Relationships
Everyone needs love and support and it is especially important for those with chronic illness. It assists in the acceptance and adjustment process, helps you cope and relationships are what makes life worth living. There is nothing more fulfilling than loving and being loved. Chronic illness will undoubtedly be a strain and stress on relationships and has the potential to erode or destroy them if left unchecked. It will be necessary to make a conscious effort to nourish them. Make those most important to you a priority and reserve quality time for them. Encourage open communication of feelings. Deal with the impact the illness has on your relationships directly and honestly. People have a tendency to try and spare one another's feelings by avoiding these types of discussions, and although you may avoid the discomfort of the moment, in the long run this is destructive to the relationship. Seek friends who are supportive and understanding.<<
