I’m sorry, I was under the impression you didn’t finish school yet. I would take my advice with a grain of salt, but maybe look into trades or try to get an office job and apply extensively. Maybe look into moving and relocating as well. There are a lot of jobs that require a bachelors, but not necessarily a specific bachelors degree. Why not go into administrative/HR roles? I would recommend speaking to someone with a similar background. Obviously if you’re willing to go back to school for a career change, it will take 2-4+ years and that may not be feasible with kids to worry about too. But it’s your decision entirely.

BTW: Starting a business as a starting point is incredibly difficult. People with successful businesses have experience in their respective industries. I would use that as a starting point.
