Six months to live

I'm knocking on death's door, there is no doubt.
After years of drinking, my heart is going to give out.
The doctors have given me six months to live.
I hope the people who I've wronged can forgive.

Over the years I've drank too much liquor.
I paid the price when I got sicker and sicker.
But I will spend my remaining time without feeling gloom.
I'm going to live life to the fullest even though I'm doomed.

(Even though this is a fictional poem, it's reality for some people.)
