I tried to shave my labia and around the vulva region and now it's so itchy

Hi, so im 15 and I tried to shave my labia and around the vulva region. Which obviously a terrible idea! I am a virgin and do not have any STI'S and I am particularily healthy , but I AM SO ITCHY. It does not hurt to pee and feels great to take a warm bath without soap and just soak! But as soon as I get up I feel the need to scratch and its keeping me awake at night! I really need a quck home remedy , becaus eot may be spring break now but I have to be in school monday and dont know what ill do!! PLEASE HELP
