I have a problem: I grieve for people that are still alive and well. My father is over sixty, and is getting old: he can't run as fast, is balding, is getting wrinkles, many of his older friends have already died... Every single time I get a reminder that he is old and might die, I just get so sad, so lost, and I burst into tears. I get nightmares of him dying. It gets to the point that I can't even eat dinner with him or go on a trip with him without having a horrible moment of "he will die someday", even as he's laughing right in front of me. Everytime he leaves to go to work or get groceries, I wonder whether it's the last time I ever see him.
I feel often terrible because of it, and fear what will happen if his condition worsens or if he happens to die.
Please, help me, I don't know what to do...
