My Chemical Romance - Save Yourself, I'll Hold Them Back Lyrics Meaning

From what I've heard, this song was written for Bandit Lee Way (Gerard Way's daughter) so that when she's older, she can look back on this song and know that she can save herself from depression and suicide and drugs, etc.

In other words, I do think it's also out there for the fans. Lots and lots of people don't save themselves, and they think it'd be better if they just killed themselves.

Get off the ledge and drop the knife
is saying don't do it, don't stop living. Because there is someone who still cares about you (like this band cares about what happens to you).

We can leave this world leave it all behind says that this place isn't perfect, but that's okay. It can be left alone. And that's all I know.
