I would tell them that I am right there with them and am ready to listen when they are ready to talk. I usually sit quietly and patiently until they are ready to talk; if not, I stay until they are. I’ve been there too many times to count alone, and I would never leave someone alone during their dark moments. I would also offer to cook a meal ot take their trash out, try and help in any way, shape, or form that I can.
