Given the circumstances that you have written about, it was proper for campus staff to ask you to remain (you were not physically restrained) at campus property while the overly intoxicated female was being attended to since you could have been a witness as to what she ingested in order for her to be attended to by medical personnel.Since you are a minor and had a .021 blood alcohol level in your system you unfortunately have a criminal matter to attend to. I suggest that you consult with a criminal defense attorney to assist you in your matter.
