Ulcers

In middle school I found out that I had an ulcer in my vagina. The doctor said that it was really rare but it happens. This past week I have had 2 cold sores on my face, strep and an ear infection. A couple days ago I notice that I started having a burning sensation when I peed and I just thought I scratched my self down there. Then today in the shower I peed again and it burned so bad I had to open my lips apart so my pee wouldn't touch them. Once I'm out of the shower I grab a little mirror and look at my vagina, there is a small sore on the inside of my vagina lips. I seriously hate this.  My mom and I aren't for sure on what it is but she thinks it is either strep down there or another ulcer. I can't believe this is happening to me. 😭😭😭
