Please help identify this song! Genre: electronic/pop/alternative, strong female vocals, Sounds similar to Ellie Goulding?

I always hear lyrics wrong so I could be way off but I think the lyrics go: "crawling/clawing/calling/falling? in my head" then that last word repeats and trails off... "head-hea-he-h" which is the identifying part of the song...

"in my head-he-he-he" .....something like that! Please help!!!

Other words that may or may not be in the lyrics are: find, mind, you, inside, me, again, when...

I've searched and listened to every song I could find with the lyrics "in my head" and it's not any of them! So I could be wrong about the lyrics!
