Fun fun fun vaginal cut

My bestfriend for almost a year now was fingering me pretty fast to get me to squirt and accidentally scratched me I have never seen so much blood but it’s been two days and I took a picture to check on the cut and it goes from the inside of my vagina to the inside of my lip but at one place thats a bit yellow but I’ve been keeping it clean as much as possible and there is some itching. Any tips on how to make it heal faster? I read online you’re only supposed to use water if it’s on the inside no soap or anything because that will worsen it. I just want it to go away. I do not want my family to know they’ll cause a big scene so I don’t want to go to the doctor. :( any help?
