4. Hold back on offering flippant advice. Please don't say that people need to just "take a walk, call a friend, or have more hope." Unless you genuinely believe those things are going to heal someone from a deadly disease, you are trivializing what suicidal people are going through. In tough times it can be great to get some fresh air and having faith certainly helps in difficult situations. But don't solely address the symptoms, and not offer support and solutions for the root cause. Try offering these types of supportive comments instead: "If you are ever in this much pain, please know that I am a safe space and we can get through this together," or "Reach out to me and I am happy to help you find the relief you are seeking," or "You are not alone."
5. Recognize that reaching out is the biggest obstacle. For a person with suicidal thoughts one of the biggest lies their brain is telling them (beyond just "you need to end this" and "your family and friends will be relieved you are gone") is that they cannot and should not reach out for help. This is the cunning, manipulative cruel nature of this "disease." Often, reaching out or telling a friend feels like they are being a burden, and shame keeps them from asking. So just throwing out the number to a hotline is tough. There are insurmountable objections in their brain to overcome before they can even pick up that phone. Stressing that they will be loved and accepted, and that we (as a society, even) will never give up on them can have a much greater impact.
6. Be open-minded and willing to not understand. If you don't understand suicide, if it seems illogical to you, or crazy, that's okay. It's shouldn't make sense! It doesn't make sense! Perhaps you don't understand it, but you need to be okay with NOT understanding. Be willing to offer grace, love, support and empathy even though you can't comprehend it. A little love and encouragement goes such a long way.
