My father is 55 years old and is a teacher. I feel he has some psychiatric problem. He hates to touch everything else his stuffs. In our home he has his separate stuffs (like soap, cumb, mirror etc) to use and no one else can use that. He always used to be extra clean than its required. After touching anything he cleans his hands with soap. Again he always judge things from the meaning of the brand. Like if the brand is like'Lifeboy' its good but if its like'Killer' then he will never use that. He always becomes too nervous when any official task is given to him without even knowing about that in detail. Whenever a problem arises he becomes tensed and tells that to us and everyone else, even who does not have to do anything with it, repeatedly until someone does that or finds a solution. Please tell me how to deal with this problem.
