Yes, I do fear death, but I do not obsess over it. Happens to all of us, it is part of the whole process of being mortal. I am far more scared of suffering a slow, lingering painful decline, or -worse- losing my mental faculties and turning into a dribbling shell.Only if you genuinely believe in an eternal afterlife of heaven and hell - and there is absolutely no evidence for that - would there be some sort of reason to be morbidly fearful.
As for wanting my loved ones to die at the same time as me - to be honest, I think this fear you have of dying is causing you to be pretty selfish, if that is what you would really want. No, the very last thing i would want would be an end to family and friends and loves just because I have come to my end. I would wish they live a happy contented and fulfilled life. hopefully with pleasant memories of me :)
