My parents let me stay up to watch Arachnophobia when I was about 6. That movie absolutely fucked me up for the longest time, and it's probably why to this day I'm absolutely terrified of bugs and spiders.
Umm... trigger warning, I guess, but the best way to fight fears that you know to be somewhat irrational is information and exposure.
This guy, https://www.youtube.com/@travismcenery2919/videos , has very deep and detailed videos about the spiders you are most likely to meet, along with some cool pressure tests of said spiders showing that they really just want to be left alone rather than hunt you.
I liked spiders to begin with (except for the jerks that spin a single invisible strand at head-height in front of my door every morning), but his videos do a good job of giving them character and making them into cute eight-eyed goofballs instead of super predators.
