Tick tock, you're on the clock.

Tick tock, tick tock;
These depressing thoughts won't stop, they start coming when it gets dark.
Even though my heart is locked, I thought I closed you out.
I guess not.
You tied my brains into a million knots, the rhythm in my brain screams at me; tick tock, tick tock, take your shot.
Tick tock, you only have one shot,
Tick tock, tickety tock you have the quick tick tock before you take the last shot.
Tick tock, tick tock, out of time.
Clock ticks, and tocks once more.
Am I too late to admit I have a problem?
