I’ve been through this…my cousin tried to kill herself by almost jumping off a 5 story building, but I was there to stop her from jumping. They get better…I promise—well, not promise, I can’t guarantee it but I hope that she gets better. Right now, just talk to her, tell her what she would be missing out of if she did die; finding love, having children, traveling, parties, friends. Tell her how much you would miss her if she really did leave this world. Tell her that the other half of you isn’t there without her. All she needs is someone to tell her “It’s fine. You’re here, that’s all that matters”.
