I have health anxiety, so anything related to my health makes it worse, I understand how you feel. I have a girlfriend who has a hiatal hernia...she just had an endoscopy last week actually, but shes had the hernia for years. She's on a prescription for heartburn and there is a long list of foods shes not supposed to eat that aggrevate the condition. I would look into what you can do to make the symptoms as unnoticable as possible so you can go on with your life and not have this add to your anxiety.
