It is also selfish of everyone else to stop her from killing herself so that they can keep her around.
And I really hate when people perpetrate the myth that "lots of people" kill themselves over trivial things. The vast majority of people who kill themselves on purpose do it because they have mental problems and chemical imbalances that make them unhappy.
Andrea literally has nothing to live for, and while logically, things COULD get better, when you are in such a situation, you are probably thinking emotionally, not like a ****ing robot. You quite simply lack empathy if you cannot understand her feelings or actions.
