I'm Stuck in My Head But You're Here Too

What's the matter with me?
I was fine before
Before you
Now I'm a mess and I don't know which way is up
You are so confusing
Sweet and soft one minute 
And cold the next
What
Is
Going
On?

I've always been self-sufficient
I've never really needed anyone
I was book smart and clever
All my good qualities 
Down the drain
Thanks to you

I've been stuck in my head
But the thing is
You're here too
I can't get you out
No matter how many times I try to show you the exit

What an unfortunate mess
I've created a monster of myself
No wait
You and your smile did that
I can't focus anymore
Not even on my favorite book
All the characters remind me of you
You and your awful hands
Awfully soft hands for someone human
Then again maybe you aren't human 
Sometimes you seem to lovely to be like the rest of us

This is just so uncomfortable
My mind has become a mush
Shaped in the letters of your name

I've always been a straight-forward thinker
Always to the point
Sarcastic
Jaded
Skeptical
Now I'm not any of those things
Now I'm just a catastrophe

How did you do this?
What kind of sorcery did you use?
I don't understand
But if I did know what you were doing 
I 
  Don't
      Know
          If
             I 
               Would
                   Even 
                       Try 
                          To 
                            Stop
                                You
