Generalised Anxiety Disorder has treatment, depending upon the severity. The options available are from medications to therapy, and a combination of both, to even newer non - medication, non - therapy options. The treatment regimen may be customised as per the patient. However, only on consultation with a registered psychiatrist or a psychologist will you get an idea as to the treatment plan that you will individually require. As to being 'fully cured' I will say that with the treatment options available, you may find much greater relief with treatment than on not taking any.
Next Steps
Consult a registered psychiatrist/psychologist on an individual basis to get a complete diagnosis and treatment.
Health Tips
No issues with a second opinion but remember it takes time for any medication and therapy to act.
