Unrequited love for life

My body know’s it
And you know it too
That sitting in these sorrows
Is all that I can do.
I reach for a hand
To pull me up for air
But I’ve grabbed at nothing
Because there’s no one there.
So I climb into my once warm bed
Wrapped in subpar feelings
The cold begins to creep in
Down through the ceiling.
The frost whispers that it’s kind
As it eats away my mind
So I lay
So I decay
I let it swallow my memories
As it morphs into them
Now I’ve watched it devour for centuries
It tells me that you are what you eat
But why is it you?
