NaPoWriMo - Day 9

Hi guys! Today I'm going to be doing the theme for day 9 of NaPoWriMo, and it's going to be interesting! I have to write something which includes a line that makes me feel uncomfortable, so this is a challenge, but that's what the prompts are for, right?

Immortality

Everyone's dead.
They lie around me
Like leaves of a fallen tree

I never meant to be the last survivor
The only survivor
It was never worth it.

For now, the world is silence
I am alone.
Forever alone.

In the cold, dead world
That's going to end, like the candle that burnt out.
And I'm going to be stuck here.

Was it worth it, to be immortal?
