I could take

Dear whoever finds this
I'm sure I won't be missed
I was a mistake
So, my life, I must take
I wasn't worthy to live anymore
So, I'm walking straight for the door
I thought of ways to do it
They're all good, I have to admit
I could take a rope
But, then I thought, "Nope!"
I could take a gun
But, that's already been done
I could take vodka and pills
But, that gave me cold chills
I could take a knife
To end my pain and strife
I could take a needle to my vein
Shooting air won't take much pain
That's what I'll do
But you'll never have to guess who?
I wrote my name on the wall
Right beside where I would fall
Dripping down the wall was ink
I left the needle in the sink!
