I would suggest you to consult your family doctor, to begin with. You may, on doctor's advice, get your
thyroid condition checked. If that and other physical health parameters appear to be normal, you may have to consult a psychiatrist (without hesitation) and get your anxiety managed, maybe with some medication, if suggested by the psychiatrist. Simultaneously, please consult a psychologist to understand the underlying conditions and situations that are putting you under stress and anxiety. The psychologist is very likely to guide/ train you to cope with those situations so that you can manage them on your own without getting stressed up.
Next Steps
Please consult your family physician / a psychiatrist/ a psychologist as required.
