5: don't sweat that so much, get minors in what DOES interest you and you'll be glad you have a thorough business degree to back up any venture you might take afterwards that goes deeper into one of your minors?
2: get other friends
seriously, it sounds odd, but if all they can think about is doing stuff with their SO, and you need to be able to do other stuff too, then find some people, or even just 1 or 2 people that you can do that other stuff with too. You say you don't know what to do? Go out and do something else, anything that interests you, and get acquainted with other people there?
1: I was stuck in the same situation. Unless you are thinking of dropping out and starting again next year at a different place, I suggest you accept it. It's dreadfully boring, I know, but you can't exactly change it. Just try and get out in the evening or during weekends to other places than your local area, might help a bit if the location you spend your time in varies a bit... then again, might not
4: probably the same as 3. You don't spend enough time doing something mentally captivating and challenging for you, a part-time job in something that you care about might help, not just during the summer, but also during one or maybe even 2 nights a week. Listen to Cyn's advice, take a volunteer job in anything that you think might help you later on (if only as a reference on a resume...)
hmm, why can't I ever respond to these things in the right order
oh well, I hope you find at least a little bit of useful info or advice in this post
