First of all, decide on what exactly you want to work. Nobody says that psychologists to total specialization can not count, but if you need a truly operational and bulk help, you should pay attention to psychologists specializing precisely in the area in which you think you have a problem .
Select several psychologists, based on their recommendations. Ask friends only if you do not fear the publicity of your problems and the emergence of rumors, in all other cases, first make a visit a psychologist and is already in place ask him about the recommendations of the patients. Be sure to call a few of them.
Remember that once you have chosen this psychologist, then, before you pass the full course of treatment, you should not change it, and switch to the other. If the previous two elections brought a positive decision, then it is really high-class professional, who must make his own decision about redirecting your case to another psychologist.
Be as open with the psychologist, if something does not know about you, he will not be able to end to help you.
