(Pretty sure I'm sx/so)
Anything that prevents my ability to experience joy, calm, or closeness with others. In other words,
1. becoming distracted or otherwise detached from what drives me: of not being able to love and properly respond
2. not being understood and loved
Fears that stem from the above: mental or emotional illness, dulled emotions, not being able to quiet my mind, isolation, losing my loved ones, certain social situations
Childhood fears: germs, every type of monster (esp. demons and ghosts; the idea of being possessed or haunted terrified me), parasites, toxic substances. all of these were extreme at one point, but I was able to rationalize my way out of them by the time I was 7 or 8
I know hardly anything about counterphobia, but I probably lean towards that. I'm pretty good about acknowledging, examining, and immersing myself in what scares me (internal or external), unless it's obviously counterproductive or not worth the risk. For example: I've also had bad social anxiety, and I tend to force myself into uncomfortable and/or terrifying situations.
I can’t imagine reacting to snapping turtles in the same way @Inari Love did haha. People tend to think I’m more phobic than I am because I might ask a question like “Can snapping turtles be deadly?” out of...I don’t know what. Even though it’s a natural response for me, it’s a dispassionate one. It’s natural for me to check and troubleshoot, even if I don’t viscerally sense a threat.
