I don't know your specifics, but here are a few ideas that may help:
1. None of this is anybodies fault.
2. My fear of living is more intense than my fear of dying.
3. My decision is a logical one as opposed to an impulsive emotional one.
4. I've been too strong for far too long, yet now my battle is over.
5. Life feels like death, yet I died inside a long time ago.
