Scared and alone

What started out as a cut now appears to be huge and accompanied by wat look to be ulcers. My first thought was herpes. I am terrified and can't stop crying as I know this stays with you for life. The pain is almost unbearable and I can bearly walk. How long does it last it's been a week since I noticed the cut? I was in denial telling myself it was a yeast infection but have come to my senses that it is more than likely gentian herpes and have an appointment tomorrow. I know they will say that is what it is and I'm so scared. Who will want me now:(. Tweet
