my vagina is really itchy, sore and red, also something white is coming out

Hey, no need to be embarrassed, sounds like you have thrush, which can happen to anyone. I suggest that you speak to your mom and see your GP to get some cream or medications to clear it up.
It is not because of something you have done, it can just happen.
Good Luck and hope you get it cleared up soon.

Thank you I'm just scared to talk to my mom but I will try thank you
