I have an extremely irrational fear of death at 19 because of how much of my life I've wasted and it's making me waste away even more of my life. I can say that to you, I hope?
Yes but it might leave me in shock, is that okay? I now need to ask you this. What are you so afraid of?
I don't want to die at all! Death scares me so much because of how much I have wasted my life.
Death is the only thing in life that is inevitable. Maybe if you can just accept that, the fear will dissipate.
That is too corny. Death isn't a good thing.
Your fear is established so you know what it is about. The next move should be to face your fear, but not saying to die now. Just accepting the fact you are going to die eventually just like everyone else could be the key, and it's not just about you might help.
