My guide

You were supposed to be my light, my guide.
Sure, you guided me, but not where you said you would.
You promised me light, yet you guided me into the dark.
You promised me life, yet you gave death.
You earned my trust but when I gave it to you, you threw it to the ground an stomped on it.
So, my trust you broke, and with it, my heart.
Everybody knows you can't live when your heart's not working
