Reasonable accommodations were offered at my school (I did my M.S. online) for disabled students. Reasonable accommodations included more time on papers, more time between classes, etc. You may consider adjusting your schedule and make one or both (school and/or work) a part time endeavor. Going to school online suited me because I could not deal with the going to school full time and working full time. The online school was full time but I did not have to worry about commuting.
