HELP ME PLEASE

I am 15, not sexually active.

My vagina: Itches, burns, is swollen, red, dry as Fuck, and hurts to the touch.

I dont know what to do. I dont know how to bring it up to my mom, and im scared to go to a doctor bc ive never gone to a gyno before. I'm just in a level of pain to where its 4am and I cant sleep because it itches and burns. It hurts when I do try to itch so I gave up on that.

I took a baking soda bath about 12 hours ago and the symptoms whent away fir about 11 hours. Someone please help me and tell me what to do.
