I can't stop thinking about my loved ones dying. I keep planning continuosly how to keep them safe by thinking about every possible worst case scenario. Even when they are safely at home I can't stop thinking the worst will happen. I'm afraid I'll wake up the next morning and they won't. I've tried to be logical about it, that the worst doesn't usually happen and that death is part of life but that doesn't help at all. I'm going insane
