My girlfriends parents are crazy, help!?

I think you and her other friends need to remind her why you like her, and keep insisting that shes a good person. You and her friends can lead by example, for instance you should not be engaging in things that are not age appropriate, which means (no drinking, smoking, doing drugs, or having ). But do not be obvious about your refusal, just make it seem uncool. Just because she has fanatical parents, does not mean she needs to go off the deep end in order to teach them a lesson. She would be better off living her life as best she can, and trying her hardest to be a decent and caring individual who strives for success without compromising herself. The bright side of this is that she will be 18 in a couple of years and not have to hear about what sort of person she is daily, by her parents who obviously do not know how to raise kids, if they allow their 16 year old daughter to go AWOL and not take positive steps to redirect her without alienating her. She will be better off!
