I'm not sure what to do about this, I'm so scared of death that I don't really enjoy my life.
Oh no, that sounds terrible, why are you so afraid of death?
I don't know what will happen when I die and I can't stop thinking about it.
You shouldn't let fear of death stop you from living a good life now. It doesn't make sense to be preoccupied by what could happen when you can live in the present now.
I can't relax and enjoy my life when I don't know what could happen after death.
I know you're anxious about death, but that's really holding you back from living your life. Talk to a therapist or possibly a priest. They could help you work through your fears about death.
