Quit my job

Yall i want to quit my job. I work for Amazon delivery driving their trucks 16.50 it’s my only source if income right now but i am BURNED out. It’s extremely exhausting 130-150 stops a day delivering 255 packages. It’s a lot. I’m miserable. I do live alone but I’m confident that if I leave this job I’ll find another asap cause I cant take this. ever been in this situation? What should i do? What would/did you do?
