Death is a release from the pain of our memories past, things that shall never escape our concious minds, tormenting us for an eternity.

Even though 'they' broke her heart, she doesn't want to fall apart. So even if missing him is wrong, it's his memory that's keeping her strong.

The ground beneath me just disappeared, and now I'm falling just like I feared.
