Eternal Sunshine in Okay

It's good that you can just cut off your emotions
It's good you can just forget your memories
And it's good that you can choose to just not feel
I'm happy for you, really,
but I wish you could've taught me how before you left
Because every time she gets close, every time she leaves
I let you get inside my skin, your presence remains
And I hate myself a little more, 
After every dumb thing and harsh word you wouldn't admit to, 
I don't want this anymore,
you exist nowhere else but in that one dark corner in the back of my head
And I want the memories of you gone
