Hi, I Am So Terrified Right Now, My Bf And

Hi, I am so terrified right now, my bf and I had unprotected sex. I have learned that I have what is called a vaginal blister upon googling, on my inner lip of my vagina. It has white puss and is not itchy or anything. It's just there. Furthermore, I also have what looks like an open sore just at the end of my vagina going to the passage to my anal. I haven't seen a doctor as I am terrified my parents will find out. It's painful when I pee. Please help. I don't know what this is, how I can treat it at home and could my bf have given it to me? . Thank you.
