Cover art for Composure lyrics by August Burns Red

I believe that the reference to scars and self-harm is both symbolic and literal, because of this line: "Button up your shirt. Roll down those sleeves. Don't let them see how you've coped."

It's not just "emo"s that cut themselves, that's quite stereotypical.

I agree that this song is just about getting through hard times and getting on with life. It also makes a reference to not turning your back on God and your faith: "Life can be overwhelming, but don't turn your back on the strongest crutch you've ever."

Though it could also be talking about friends: "They have always been there to brace your fall."

I think the video is also symbolic, because it shows the man being beaten up, and it turns out that it's himself beating himself up. It's suggesting that the man is his own worst enemy, and again referencing self-harm or abuse.

At least that's my take on it.
