If you are being harassed and tormented by your university roommate in assigned university dorm units by your school, I would set a written record of the problems that you are having with your roommate and first go to mediation after you have requested an assignment to another room to the university housing.If the mediation does not resolve the issue where you get assigned another roommate by university housing, your next option is to consult with a landlord tenant attorney about the unhealthy situation that you are in and how to get reassigned another roommate.Good luck.
