Read this. It might give you a bit of perspective. http://talk.qa.collegeconfidential.com/t/to-those-who-feel-lonely-homesick-friendless-think-they-chose-the-wrong-school-etc
Is the problem you, or the school? Did you have unrealistic expectations? Because your post is so vague, it’s hard to know what the issue might be. I think @collegemom3717 is spot on.
Re apps being due in March (typically mid March for Ivies, etc…), you’re going to need really great prof recs if you hope to transfer to schools even more selective than Tufts. So even if you aren’t loving your time there, you should still put your best effort into your classes.
