scratched vagina?

soo i have long acrylic nails & when i have a little itch down there.. im not too worried about ya know, handling my business. soo a few days ago, nothing out of the ordinary i had an itch. i scratched my kitty cat & i guess i scratched too hard because now theres like a tear ???? it hurts like hell when water gets on it in the shower so i’ve been extra careful to keep soap away too. im scared its not gonna heal because its been a few days & this shit hurts!!! what do i do ??? has this happened to anybody else ??
