How Do I Get Out of This Hell Before I Burn Up?

I asked for the job I have now because I need the money. I have a family and the bills never stop. I’m so tired all the time and my schedule doesn’t seem to jive with my family’s at the moment because I’m up at 4:30 AM every morning. At night, I’m hardly functional by 8:00 PM because of how exhausted I am. I’ve been trying to get to bed earlier but bedtime isn’t always within my control.

What hell have I gotten myself in to?

Applying to other jobs has been a futile effort even though I try often. The hardest part is not becoming discouraged and believing all the negative things I say about myself in my mind and more importantly in my actions.
