Hi, sorry to hear the awful news, it is not your fault. You have been a victim of someone elses carelessness. You have to deal with it now. You sound quite young. You need to get some hydrogen peroxide liquid, 3% and put it in an atomizer and spray the area, that will help to dry it up. Keep all Sugar out of your diet while you are trying to clear this up. (you could try the Neem oil).
Do whatever it takes to heal yourself, and get your life back. Nobody has to suffer with herpes these days, God has made a cure for everything. The neem oil is very good, but while you are taking it, it acts as a natural contraceptive, when you stop taking it, fertility returns. I have found taking 1 teaspoon of neem extremely effective. It will clear up within 3 days but you will have to continue with it, to be outbreak free.
Good luck
