What does one even do in a situation like this....

So I have this one friend who gets extremely touchy with other girls, grabbing their boobs and stuff. Usually we just laugh it off cuz we're friends and today she literally PULLED DOWN my pant AND panties infront of the WHOLE CLASS and everyone saw my coochie bro.....
I yelled at her really bad, went to the washroom and SOBBED. it was embarrassing, shameful and I was so angry. I just left early and avoided them, she came to apologize saying it wasn't on purpose but like would you just accept it and get back together in such a situation...?
Now I don't know how to face anyone tomorrow and I can't complain about this to anyone else either because they're not going to take it seriously. I just want to disappear I hate this
