I thought “no one wants to work!?”

I recently quit my substitute teacher job (not really lol school ended) but I don’t want to come back to it. Neath less to say I been applying and no one is calling back. I’m desperate don’t want my car be repossessed. I been mostly applying through indeed and job agencies. One job agency told me I don’t qualify for any jobs even though I have a BS in math. Indeed is useless. Anyway anyone could help a brother out any advice?! I would appreciate it a lot.
