As far as I know, there are two treatments for OCD at present. The first is medication, the second is behavioral therapy. I wouldn't recommend the former, but behavioral therapy can work wonders. For behavioral therapy for obsessive-compulsive disorder, you need to carefully choose a doctor - I would recommend a couple of sessions just to talk to him, rather than start right away. In the vastness of our country there are too many unskilled psychologists who put people on medication and do not shun primitive NLP.
But, even if you do not go to a specialist for treatment, but choose some other method, do not blame yourself for being its owner.
It's impossible to get rid of such a neurotic nature of the disorder just like that. And the prognosis in this case is unimportant - obsessive-compulsive disorder is poorly treated, the result is rare. But it's worth trying! A psychiatrist and a psychotherapist in a community may well make a person's life much easier - to reduce the level of anxiety and suppressed emotions, which means that obsessive thoughts and movements as a protective function of the body can be replaced by other, lighter ones.
In this case, psychotherapy is needed for a long time and in any case it will give relief and greater freedom from inner fears.
