What should I do I'm scared?

I went to the minute clinic at drug store to see a nurse. I couldn't get into my doctors office.
I had my tongue tingling. I thought it was the Prilosec I was just prescribed for my GERD.
The nurse said it was just food allergy an id be fine. She then checked my eyes with a flashlight and said I have a ring around my eye. It looks like it might be glaucoma an I should get it checked out. I'm terrified. I don't want to go to the doctor and get bad news. I usually don't go to doctors or the hospital. I'm trying to go to graduate school. I'm studying for an entrance exam. I don't have time for this. I don't know what to do. No one in my family has glaucoma. Only a great aunt. But that's not immediate family. Not my parents grandparents or great grandparents. She said its hereditary. Well I couldn't inherent it from my great aunt. I don't know what to do. I'll never go to the doctor again. They're always trying to ruin your life.
