Recently I went to a general doctor for a symptom, and he said I may have something, and referred me to a specialist. This something turns out to be potentially precancerous. I had no choice but to panic for 2 weeks until I saw the specialist who said it's not what the general doctor said, and it's not serious. Sometimes, doctors themselves may cause the anxiety. But yes, googling symptoms is a bad idea. It turns my anxiety into panic attacks most of the time.
