As a child, I had a fear of falling. My dad promptly caught onto this and put me through multiple summers at a Ropes course. That and a couple helicopter rides fixed the issue.
Then there were bugs, not all bugs, just the big ones. I would even casually pick tic off of my neck after an adventure in the woods but would flip my shit if a dragonfly landed on me. This lasted for a while, but kinds just went away over the years to the point where I really don't care what wants to land on me.
The only fear I might still have is the fear of an afterlife. I see death as a final end, a great sleep where I can rest from the stress of life. I desire a sudden death, but I know I might have to deal with a slow and agonizing one. I have accepted this and moved on, but the thought that I might continue and linger on, with the experience of that loss of life, scares me. I don't care if I could go to heaven and forever be drinking partners with Jesus, I just want a well-deserved rest after my life.
