Good for you! We all need to stand up for ourselves, regardless of the problem.
I hope that you've documented all of your attempts to get assistance from the college and if you have not, start doing so immediately. Although it's not likely, I'd hate it for them to try and turn the table on you and say that you are the person creating the problem. Hopefully now someone will finally start to listen and remember - DO NOT ALLOW ANYONE TO PUT YOU IN A POSITION WHERE YOUR HOUSING COSTS INCREASE. It is the college's responsibility to place you in an environment where you are safe and comfortable. They are required to make accomodations for you based on your disability and doing so should NOT come at an additional cost to you.
