Plant Problem

Plant Problem

Hey all, new member here. I've been having a problem with a plant I got two weeks ago. It's a kind of lily plant, though I don't have the exact name (it's similar to a Peace Lily I think). I had it for a week at home, and it seemed to be doing alright, but it's been in my dorm room a week, and some of the leaves have been turning black. It's lost almost 10 big leaves already, and more are changing color. I think it's getting adequate sun and water, and the other plants in my room are doing fine, so I can't figure out what's wrong with it. If someone has some ideas as to what to do I'd appreciate it. I'm starting to get worried :(
