You may have a friend who is struggling with suicidal thoughts. Your job as a friend is to be their friend an support them through it. Don't underestimate the value of caring about your friends, even if you're not able to actually treat their suicidality. Remember that there's an equation between pro suicidal factors and anti-suicidal factors. You don't want your mind and your emotions to be in control of you. And do you want to listen to your mind? So be careful, right?
