If you want to come out of it completely,  then it is the responsibility of the person to work on the techniques and tools consistently and with some follow-ups  with a psychologist.

Hi. Anxiety can be a symptom of many psychological disorders. Its very difficult to infer what you might be suffering from since you haven't mentioned your symptoms in detail. Obsessive compulsive disorder usually responds well to treatment. The treatment consists of a combination of medications and psychotherapy. And the symptoms can be completely controlled if you remain on treatment. Sometimes, it might be necessary to continue medications for a very long time.
