Hypochondria is the pathological concern about one’s health. The splenetic (person having hypochondria) constantly monitors his own state trying to define the disease or diseases which he is sure he has. He is in constant web search of the proof for his false symptoms and nothing can persuade him that he is all right.
As far as you can understand it is very difficult to live along with such a person. If you don’t admit him being seriously ill you become the number one enemy. But there are some tips that can help you be more comfortable about it and together with that they can probably be helpful for the splenetic himself.
