Dealing with Thanatophobia: Coping Tips Needed

I have it and have put myself in so many panic attacks over it. I'm absolutely mortified at the thought of it honestly. There's such a huge fear for me about just not existing and continuous darkness...

Have you talked to a therapist about this?

First, you should start by going to take a long hot shower or bath. Take care of yourself first. Wash your hair, brush your teeth, the regular hygiene routine. Then drink a glass of water, whatever temp you prefer. I alternate between cold and room temp, hot sometimes as well because hot water is actually good for your digestive system. But get something decently balanced to eat. Make a list of your 5 top chores that are priority. And tackle one chore today. Although death cannot be avoided, life can't either. I have experienced many losses. And with each one, I learned to say that, I am grateful to have gotten to know them, or if it's family, I am grateful to have been there relative or whatever title, and be thankful for the memories. I did my best to turn the sadness into moments of appreciation and genuine gratitude. And it helped. It didn't hurt any less but it helped to quite my thoughts.

Well I don't know if it's a good tip, but believing in a religion, should make you feel like at least you'd go somewhere safe when you die.
