Finding people with whom you click is not easy in the large context of uni. I hated my first term - the place seemed to be full of upper class Hooray Henriettas all brimming with confidence and pzazz. I felt like a right country mouse - boring and swotty.
I changed my accommodation in my second term and things looked up - I met folk who chimed with my life outlook and with whom I could have the sort of fun that I enjoyed. I joined some societies; and also a choir in the city.
It is important not to lose your self-confidence. Just because you feel out of kilter with where you are at the moment is not a reflection on your self-worth. You do not have to be like your room-mate - you have to be like you, and proud of it.
It may be that in the end uni is not for you; and it is not true that employers only want a degree. They want people with integrity and loyalty and a willingness to work hard. There are many qualifications (including degrees) that you can do at your local college; there are training schemes run by companies; and there are apprenticeships.
What really matters is that you should be happy. Some of the best qualified people I know are some of the unhappiest!!
If you feel that you want to get this degree at this uni, then you have to go all out to make things right for you. Talk to people - the student support, your tutor, the accommodation people, your family. Don't let this get you down - it is simply not worth it.
I wish you lots of luck in the future - remember, the future does not just happen by itself - a lot of the future is made by you!
