I've never been in a situation where I had to live with a roommate. I took college courses at the technical college here in town and still stayed at home.
The problems I come across sometimes are on the job and also just making friends in general. Most people, I do not say anything about my hydro to unless they're sincerely asking about it and want to know. Once I feel comfortable with the person, it's OK. But I HAVE had my share of being made fun of, and it's a hard situation especially since there are some scenarios where I cannot control who the people around me are (group situations at school, classmates in general, etc...). I would maybe talk to the special needs department and see what can be done. There has to be something. Some students they know of that are compassionate and understanding...etc...but I know how the poor guy feels.
