Cover art for Your Bruise lyrics by Death Cab for Cutie

i actually think this song is about self harm/self abuse.

It is not about his abuse, obviously, but the girl he is talking about. Let me explain:

"Its a backward attraction to your forward mind" By cutting herself she is trying to move past her pain, but in reality it is setting her farther back into her pain/depression. It is a temporary relief.

"but youre so far-sighted you cant place trust in what or who you recognize" She cannot meet somebody and trust them, even if she has trusted them previously. after whatever traumatic event she experienced, she now can only see to the future when people leave her or hurt her. Therefore, she cannot trust anyone.

The whole next verse is obviously personal/about a trip where he had spoken to this girl. "All these secrets started giving me the shivers" The secret about her self harm/depression/whatever caused her to start hurting herself.

"I think your bruise was understated" This is what really made me think it was about self harm. It is the quote of all self harmers 'it's just a bruise, it's just a cut.' He is saying this is understated, and it is a way bigger problem then simply a bruise. It spreads to so much more in-depth pain.

" because you cant feel this anymore" Many cutters use self harm to become apathetic. Their brain reacts too strongly to the adrenaline and it creates a calm, a numb, a temporary relief. Most self harmers do not actually even feel pain upon cutting/hurting themselves..only adrenaline. He is saying the bruise is understated because how numb she is becoming to the rest of the world.

"its getting bluer and you cant keep faking that you cant feel this anymore" Again, she continues to fake happiness or at least apathy through cutting. But like any addict, you get used to the regular dosage and eventually need to hurt yourself more than you initially did. In other words, though it may have been a small bruise that created the numbness before it is now a huge, deep, dark blue that she requires to feel numb.
