In which case I'd focus on building up your education/job skills in a field that would allow remote work from home. Or, while you mention crutches, accept that a wheelchair might be a necessary option, and look for in person jobs that can accommodate you getting to/from the place in a wheelchair. I'm not naïve, and it will certainly be harder than it was before your injury. But people thrive in work/life with similar mobility issues all the time.

Contact the public transportation authority where you live. There may be a program that sends a mobility van to your doorstep and takes you directly to your destination. This would greatly improve your options for employment if the transportation piece is solved.
