I went from a government employee to a customer service representative agent.

I'd say that's an upgrade. People can say what they want but at the end of the day, your current job will pay the bills and more. Plus, there are lots opportunities for promotion and career growth.

I'm in a graveyard shift so after work, when I get home, I sleep the day away to replenish my energy for another night's work.

Once your body clock adjusts, it will be easy breezy. Have fun!
