There are several threads on this site discussing views on the value (or lack thereof) of college education for a stage management career that you may want to look at. Does your city have non-equity theaters? Non-equity venues can be a great way to build your work experience. If you're open to work that is not strictly stage management (overhire lights/carpentry, run crew), that could be a way to get your foot in the door at the equity venue.
Another path would be relocation. You could move to an area with more options for theater employment. You could also look for internships or apprenticeship programs; many are not tied to colleges. I think there tend to be additional options for short-term theater employment in the summer, some of which provide housing, so that might be something to look into for next year to build your resume.
