OMG!!! I think I have yeast infection! 😩

This incessant itch in my vagina started 3 days ago and I don’t know the cause of it. It itches like crazy I don’t even know how to explain it. It feels like that good itch like when you masturbate I don’t really know how to explain. It doesn’t sting when I pee but this white discharge comes out and I don’t even know how to explain it. Then I took a picture of my vagina and I saw that my clitoris is discolored, like it’s red and weird than the rest. I really wish I could share that with you guys to tell me if it’s really a yeast infection. I’m scared and I don’t know what to do. I wanted to ask my mom but I’m afraid she’ll blame it on having sex with my boyfriend. I don’t have insurance so I can’t see a doctor. I’m so scared, I don’t know what to do. I really don’t know where I could have gotten it from but I think it’s from either the toilet at work or school.
