Having the euthanasia option is what is giving her the strength to live. This is a lot more common than most people realize. When people fear losing that control, they often take their lives before it can happen.
@Suppressed The people who fear losing control need to realize that they aren't primarily in control in the first place. God is.
Sure, we can take temporary control from God with our selfish decisions, like choosing homosexuality over the gender role God assigned you, but it just puts you in a place incompatible with Heaven, especially if you are prideful enough to think your finite control in the temporal world is significant compared to God's infinite control of the Eternal.
