Did It to Myself

I woke up to an empty bed
 I took a walk to clear my head
 I wished you were there instead
 But then I shook it off
 What the hell did I used to do?
 I'm even starting to speak like you
 And now you're living in my memory
 Living in my mouth
 Living in the four fucking walls of my house
 I feel like a letdown
 To not be your friend, now
 I, I feel like a letdown
 And now you're gone, gone, gone
 I know I did it to myself
 I know I did it to myself
 I know I did it to myself
 I know I
 Oh, I know I did it to myself
 I know I did it to myself
 I know I did it to myself
 I know I
 Your personality's split in two
 I fell in love with a half of you
 And when you told me what you went through
 I couldn't brush it off (Brush it off, brush it off, brush it off, brush it off)
 I wonder what are you doing now
 Defeats the point of shutting you out
 And now my part of London feels so haunted
 You gave me a power that I never even wanted
 You said, "I feel like a letdown
 To not be your friend now"
 I, I, I feel like a letdown
 And now you're gone, gone, gone
 I know I did it to myself
 I know I did it to myself
 I know I did it to myself
 I know I
 Oh, I know I did it to myself (I, I)
 I know I did it to myself (I, I)
 I know I did it to myself (I, I)
 I know I (I, I did it)
 Oh my god, you're everything I know
 Let it sink in right now
 Oh my god, you're everything I know
 Get ready for the comedown
 Did it to myself
 Did it to myself
 Did it to myself
 I know I
 Did it to myself (I, I)
 Did it to myself (I, I)
 Did it to myself (I, I)
 I know I (I, I)
 I know I did it to myself (I, I)
 I know I did it to myself (I, I)
 I know I did it to myself (I, I)
 I know I (I know, I know, I know, I know I)
 I know I did it to myself (I, I)
 I can't blame nobody else (I, I)
 I know I did it to myself (I, I)
 I know I
 You said answer honestly
 And I went with option B
 I lost you and you lost me
 I can't shake it off
