Roomate issues

Ok, so I transferred to a new college this year, it’s my first time living away from home. So I used my college’s little forum to find a roomate. I talked to a couple of people, and told them I would potentially like to room with them. Well, my current roomate went ahead and told the lady in charge of housing I wanted to room with her, but I didn’t think anything of it. I thought she would be a great roommate from the way we talked. I was wrong. The first day was cool, I hung out with her and some of her friends, we occasionally coated with each other. But things just started to go down hill. I think one of the main issues is oureally schedules are totally out of sync, so we barely see each other during the week. Nowe when we had to feel out evaluation forms with our roommatesite, I remember her asking me if the lights bothered memail, and I said no, she said she good because it was an issue with her past roommate. I have no idea why she asked me this because whenever I am up doing homework, she will usually turn on my desk lamp, she used to ask now she will just do it. Sometimes she will leave all the lights off. The thing that makes me so mad, is sometimes she will still be up on her phone! Call me crazy, but isn’t that a little inconsiderate? Now there have been times where she will stay up till 2 or 3, or come back in the room at like 5, and I leave the lights on for her. I don’t do this all the time anymore though, since she can’t seem to do the same. I understand her turning off the lights when she is actually sleeping, but when she is up, she could leave the lights on seeing as I am doing homework. Another issue for me is that she is super messy! So, we have a triple room with just the two of us because our 3rd roommate decided not to come to the college. So she uses the bottom bunk to sit on, with no sheets. She leaves books and trash all over the bed, and under it. About a month ago my sister came to spend the night so I lent her an extra pair of my sheets. When she left I hadn’t taken them off yet, sor my roommate decides to put all of her dirty crappie on my sheet! So when she went to take a shower I took them off. She also leaves her dirty clothes all over the floor, it’s ridiculous! Another thing, so when we are both doing homework in our rooms, I’ll put on my headphones out of consideration, she however won’t. She also talksaid so loud on the phone, which is irritating when I am trying to take a nap, when I get on the phone and see that she is sleeping or studying, I step out. She also hasaid this weird habit of jumping up and down across the room, I don’t say anything or make any comments I just letc her be. We really don’t talk much, whI checked dosen’the help me since I am extremely quiet as it is. At the beginning of the year she told me she was hoping to make a friend with her roomate, but it does not look like that will happen. So, what do you guys think, am I bwing completely unreasonable? Is she? Also I know I should talk up more, bit it is rather difficult for me and I don’t want to come off as rude. Suggestions are welcome!
