A few days ago, I made the mistake of smoking weed in my dormroom. My room mate (who was a friend) now will not talk to me, and send people in little by little to get her things. She also will no longer sleep in our room. I know I messed up, I sent her texts, I apologized countless times. I feel terrible I can no longer sleep. I can't eat, I'm not going to class (I've missed a test since it happened, even). I'm full of nothing but utter guilt and shame over it. I know I messed up, believe me. What should I do?
