"Call of the void." It's pretty normal but considered taboo to talk about in most cultures from what I've seen. I think it's more common in people with mental health issues, especially OCD and depression. I experience it a lot, and unfortunately it never gets any less real, but I am less afraid of it than I was when I first started feeling it. You're not alone, friend.
I mostly creep instead of comment but I always enjoy seeing your comments on posts.
Sorry I can’t offer much to help but kind words.
