Give it a try, if you really don't like it, transfer to another school. Also, the whole not wanting to leave home is only natural. There's a bunch of advantages that come with going away to college, but there's also the downside of leaving the family, the homemade meals, the comfort of your own home. You'll probably get used to it and enjoy college life more than you ever expected!
Even with your low expectations, give it a try. Who knows, you might like it after all. Do your best to get involved, meet people, make new friends, and I'm sure there's some pretty decent and nice people among those you didn't like.
Good luck!
