Chill and relax ,
she has to experence these things for her self , just like with kids , some time time you just have to step out of the way and let them slam their heads against that wall them selfs , you be there to help pick up the pieces and clean up the blood( oh and none of that "I TOLD you SO" Bullshit!!!! ) , but they HAVE to learn for them selfs , you TOO by the way ,
Just cause you are in your first year in collage doesn' t make you the font of ALL knowlage , chill , smoke a dube , have a beer , etc,,,
Life will go on , the sun WILL raise and set no matter HOW freaked out you get about it, just learn to enjoy the ride
