Basically the song revolves around the chord progression of Dm Bb and Gm
In some points like bridges you may add some C and F, but, as the lyrics part 
goes, I think you can use these three chords.

Here's the lyrics:

Falling through pages of Martens on angels
 Feeling my heart pull west
 I saw the future dressed as a stranger
 love in a space-dye vest

Love is an act of blood and I’m bleeding
 a pool in the shape of a heart
 Beauty projection in the reflection
 Always the worst way to start

“But he’s the sort
 who can’t know anyone intimately,
 least of all a woman.
 He doesn’t know what a woman is.
 He wants you for a possession,
 something to look at like a painting
 or an ivory box.
 Something to own and to display.
 He doesn’t want you to be real,
 or to think or to live.
 He doesn’t love you, but I love you.
 I want you to have your own thoughts and ideas
 and feelings, even when I hold you in my arms.
 It’s our last chance…
It’s our last chance…”

Now that you’re gone
 I’m trying to take it
 Learning to swallow the rage
 Found a new girl
 I think we can make it
 as long as she stays on the page

This is not how I want it to end
 And I’ll never be open again

“…I was gonna move out…ummm…
get, get a job,
 get my own place, ummm,
 but… I go into the mall
 where I want to work and they tell me,
 I’m, I was too young…”

“Some people, gave advice before,
 about facing the facts,
 about facing reality.
 And this is, this without a doubt,
 is his biggest challenge ever.
 He’s going to have to face it.
 You’re gonna have to try,
 he’s gonna to have to try and,
 uh, and, and, and get some help here.
 I mean no one can say
 they know how he feels.”

“That, so they say that, in ya know like,
 Houston or something, you’d say
 it’s a hundred and eighty degrees,
 but it’s a dry heat.
 In Houston they say that?
 Oh, maybe not. I’m all mixed up.
 Dry until they hit the swimming pool.”

“…I get up with the sun… Listen.
 You have your own room to sleep in,
 I don’t care what you do.
 I don’t care when.
 That door gets locked,
 that door gets locked at night by nine o’clock.
 If you’re not in this house by nine o’clock,
 then you’d better find some place to sleep.
 Because you’re not going to be a bum
 in this house. Supper is ready…”

There’s no one
 to take my blame
 if they wanted to
 There’s nothing to keep me sane
 and it’s all the same to you
 There’s nowhere to set my aim
 so I’m everywhere
 Never come near me again
 do you really think I need you

I’ll never be open again,
 I could never be open again.
 I’ll never be open again,
 I could never be open again.

And I’ll smile and I’ll learn to pretend
 And I’ll never be open again
 And I’ll have no more dreams to defend
 And I’ll never be open again
