Swift - Lovesick

Killed--but i'm still struggling, to hold on to
You--i know i'm failing. it feels like my arms
Are tied to my hips, and i, just tripped i'm
Falling--

But not because i'm lovesick or am i lovesick?

It felt so warm with you and now my own bed
Feels foreign to me--i guess i just hate things,
That are empty and i'm sleepy--

But not because i'm lovesick or am i lovesick?

It seems like my world is falling to it's end,
It seems like the color gray.

Pictures in perfect color with words to listen to,
That's the scene i saw--and now, that my hope is
Crushed, and fingernails are gone, i'm bleeding--

But not because i'm lovesick or am i lovesick?

Please don't hold out on me, the distance cant be
That far, it can't be--this is confusing me, what's
Wrong with me? what's wrong, with me?

I'm not lovesick or could i be? i'm so--confused
What's wrong with me?
