Safety on the trigger

You're my last step out the door, the first breath I will take
The last chill that I'll feel, the only smile I will fake
You're the burn on my tongue, when I swallow you whole
You're the once sharp words, that have now turned dull
You're that fading feeling, that old once love
You're part of the past, that I've come above
You're the blurred vision, the intoxicated waste
The last truth I'll swallow, of a bad after taste
You're the safe on the trigger, that I dare to pull
Aimed for the lie that thought me a fool
