Single for Disabled Student

<p>How hard would it honestly be to get a single as a freshman?
My parents requirement is that I live in student housing but the idea of a roommate is daunting.
I've got a 504 (special needs plan) for anxiety disorder, SEVERE fatigue, and insomnia and my coping methods for these problems tend to be rather ocd (structure not cleanliness).
I wouldn't use this example with colleges but I missed a lot of class in high school because when I don't get enough sleep my body can't recuperate.
I'm getting a lot better, (I'm being medicated as if I have narcolepsy), but the nerves part obviously is still present. </p>

<p>If I was able to get the dorm is it possible to avoid segregation? Also would aid extend to the cost difference?
I know that's all a little school dependent but generalize for me please.
Or if you know anything about the policy's at Smith, Mount Holyoke, Occidental, Pitzer, and Pratt please tell.
I'm cautious about asking the schools themselves until after I get in.</p>
