Two sides to every story. Your friend isn’t your therapist and while instantly reacting with “go call hotline” means you don’t have a friend at all, you cannot expect your friend to be able to bear the weight of your feelings, of your darkest moments with you. Stuff like this ruins people and I know that from experience from both sides. Dealing with suicidal thoughts of other people is extremely stressful and basically a landmine field. You aren’t trained to navigate it properly. You are not objective. And ultimately, other than being a sympathetic ear, you are unable to help them in the way they need help.
