Hey there littleturtle! I'm very young, but I am also terrified of dying. It's something I've been thinking about since I was 10 years old. I remember being in my bed and my eyes tearing up because I realized there would come a day when my mom wouldn't physically be here. I've been thinking of death and my mortality for a long time. That's why I always try my best to tell the people I care for that I appreciate them. I always worry about how or when I'm going to die.

Thinking like that is normal and I think everyone is afraid of dying on some level or another.

I wish this was more helpful, but I hope you're doing well.
