I only work here - A way to say you're stuck in a bad job and you're too tired

A way to say you're stuck in a bad job and you're too tired to leave. You're like a dog that's been beaten and doesn't want to fight back.

I only work here because I'm too tired to even think about leaving.

I only work here because my boss is a monster and I'm too tired to fight.

I only work here because I'm too lazy and too tired to make a change.
