Mental disease
A happy family life depends on many factors. Sometimes it is not a family coach who is to care about your family happiness and work out a plan of a family successful living. No, sometimes people really need a professional help – of the psychiatrists and mental doctors.
There is a sad statistic that family tyrants are usually those people who suffer mental disorders. The symptom is aggressive behavior which is replaced with the paroxysms of regret. Then he/she asks to be forgiven praying that this attack is for the last time. But comprehension of all-forgiving makes him/her be crueler later.
Unfortunately, an attacked person does not understand danger quickly. It is used to think that everything will be fine, later, not now, but later... and a person does not abandon hope for the better times in spite of the aggressive quarreling, cowed children, and beating. But nothing promises to be ok.
Other symptoms of mental disease are unusual behavior, calmness, ignorance, estrangement, loss of appetite. A very bright example of a family person who is going off his head is presented in a movie "A Beautiful Mind".
They are not guilty about that. Simply, one day everything went wrong, but now they need help.
