I feel you. My kid at Stanford never got to have mid-night deep discussions with his roommates during his freshmen year because all of them were so busy and hung around with the kids who had the same major. For most part, I think it’s not a good idea to throw in kids with different interests and expect them to learn from each other; I think this is why Stanford is changing their residence operation system. I visited Stanford cafeteria many times, and there are many kids eating alone, whether by choice or not. It’s not easy to develop good friendships in this age of iPhones and texting. Hang in there, try to exercise to generate some endorphin. Sometimes this period of aloneness might be a good time to learn to really like yourself.
My point is what you are going through is not unusual, and I believe is a symptom of a deeper problem for this generation. When you have too many things to do alone, such as texting, watching movies on your computer, exercise etc., it becomes harder to connect.
