Visiting therapist is it good idea??

Visiting therapist is it good idea?? Are there people who have tried going to a psychiatrist to improve their condition? I am thinking a lot about visiting a psychiatric clinic to solve the problem of stuttering because it is a big obstacle in my life. Have you tried going to a psychiatrist and did he help you with the issue of stuttering, social phobia, low self-confidence, etc.? I want to hear your opinions.
