Congrats to you! Dont ever give up! I am also a single mom working full time and going to school full time. So I know how hard it can be. I would first suggest that you should contact your financial advisor at your school and see what financial aid or grants you can apply for to help with school and living expenses. Also, I know that you have tried restaurants, but have you tried temp agencies? A lot of time they have work for part time employees and can work around your schedule. Have you asked your school about work-study? They also may have jobs available. Lastly, have you tried your childs daycare? Do they need any help? Perhaps that could help you cut down on some of these costs.
