My wife I suffering from Necrophobia. Her fear started by seeing a death ceremony of some unknown person. She says that she gets bad thoughts unnecessarily which she can't control. Even her day to day work has got affected with this fear which doesn't allow her to finish anything at once. For example, she takes lot of time to finish washing even after washing a vessel, she is not able to walk in or out of house or room in a single step, she takes her step back many times to get in or to get out.
