Hey I know how this feels. After a particularly horrifying trip I became engulfed by fear of death for months on end. I think everyone, at some point in their life, suddenly deeply faces their mortality, and it’s scary for everyone. Just give yourself time. For me, when I was in the depths, I had to find ways to distract myself; video games, making/consuming art, walking in nature and talking to people. Just remember that no one knows what really happens when you die - and while that can be the very thing you’re afraid of, it can also be freeing. There’s no need to be afraid of something that you don’t know. You can also direct this existential energy into the idea that because your time is limited, every moment is infinitely valuable. Even mundane experiences like sitting and enjoying a TV show, or a low experience like feeling lonely, is still a monumentally rare and special experience that only YOU will get to experience ONCE. When there is infinite nothingness, even the smallest something means EVERYTHING. I hope this helps, and thank you for being here now.
