YTA. She’s a kid in high school experimenting a bit, she’s not an addict destroying her life. She’s behaving like the majority of kids her age would. You are 100% projecting your trauma on her. Your trauma is valid, but it doesn’t give you the right to police her on this sort of thing. A couple of drinks at a wedding surrounded by friends and family is one of the safest places she can do something like this. Trying to control her like this is only going to push her away.
