When you have a chronic illness such as CFS and/or FM, friendships vary in tolerance of illness-related issues. Some continue relatively unchanged, some become closer, and some dissolve. A balance of ill and healthy friends offers both the support only others with your illness can provide, as well as contact with the outside world. Characteristics of friendships vary, with some revolving around shared interests or activities and others based on common traits or professions. Some are just for fun – humor, movies, leisure activities. Deeper relationships will involved more intimate sharing, of course. Having a variety of friends will help reduce boredom and loneliness.
